For dogs who pee indoors, this behavior is often related to a lack of physical exercise or anxiety, both of which humans can help attenuate with the help of a vet or trainer. It could be a sign that he`s not so happy about your behavior.
A dog marking or peeing in the house can happen for a variety of reasons. One way that dogs communicate is through their urine, so they can mark for territorial reasons, as a response to stress or anxiety, or because of hormonal influences in intact males.
It`s an instinctual, physical response called submissive urination, and it`s normal in young dogs. Submissive urination typically happens whenever a dog feels excited, shy, anxious, or scared. It also happens when a dog wants to acknowledge another`s dominance — like recognizing you as their owner.
1) Aggression towards strangers

it is usually because they were either bred to be guard dogs or they were not fully socialized as a puppy. When a dog encounters someone they feel uncomfortable around, they want to increase the distance between them and the person.

Eliminate odors wherever your dog submissively urinates, especially if they aren`t completely house-trained. Don`t punish or scold them for submissive urination. This will only make the problem worse. If your dog is extremely fearful, ask your vet about medications that may help during the retraining process.
Dogs do not pee out of anger or when they get mad. Anger, or frustration, rather, in dogs can manifest in a whole host of unpleasant ways, but “anger pee” is not one of them. Dogs do, however, often pee from just being overstimulated or excited, which can sometimes be mistaken for “anger” by humans.
Marking in Other People`s Homes

Sometimes, an accident is not an accident at all. A dog that tends to mark may see an unfamiliar home as a territory waiting to be claimed. If your dog marks, you most likely know the difference between marking and an accident.

Some of the most common reasons doggos poop or pee inside after walking include medical issues, substrate preferences, and poor potty-training at the outset. Go easy on your dog. House-trained dogs commonly have accidents due to stress, a change in environment, or illness.
Submissive urination can be a problem for guardians, but keep in mind, that in dog language the dog is doing everything he can to convey the message “I am no threat.” The problem usually disappears as dogs mature, gain confidence and become comfortable in their surroundings.
When your dog exhibits submissive behavior towards you, he is usually trying to show respect and affection. It may also mean he trusts you and is comfortable being vulnerable around you. He may see you as the dominant member of the relationship, but that does not mean you need to change your behavior in any way.
The best way of treating aggression towards strangers is to prevent it by socializing your dog when they are young, exposing your dog to lots of different situations and people in a safe, controlled environment, and teaching your dog that strangers are not a threat to you or him.
Avoid triggers. You cannot expect your dog to behave until they have learned how. For example, if you know your dog has become more aggressive in high-energy play situations, stop going to the dog park until your dog has learned to remain calm. Reinforce calm behavior with rewards.
If you work from home and separation anxiety isn`t a problem, your dog may well be peeing from boredom or the want to attract your attention. He understands that peeing in the middle of the room will force you to get up and respond to him.
Citrus. The citrus smell is arguably the best dog repellent there is. You do not have to do a lot. Simply peel an orange or a lemon next to your dog and you will observe it leaving the spot immediately.
Pets Aren`t People

Dogs and cats don`t urinate or defecate out of spite or jealousy. If your dog urinates on your baby`s diaper bag, it`s not because he is jealous of, or dislikes your baby. Likewise, if your cat urinates on your new boyfriend`s backpack, this is not his opinion of your taste in men.

One common trigger for submissive peeing might be when strangers approach your dog. If this happens in your house, try asking visitors to ignore your dog until they approach on their own.
A dog who occasionally urinates in the house might not be completely house trained. His house training might have been inconsistent or it might have involved punishment that made him afraid to eliminate while his owner is watching or nearby. Some dogs urinate in the house because they`re scent marking.
Dogs often mark new items – especially if they came from a place with other dogs. It`s also common for dogs to mark when visiting a hotel or someone else`s home. While marking is often thought of as a male dog trait, females do it too!
Baking soda, vinegar, and enzymatic cleaners are all effective at removing the odor. In some cases, you may want to avoid steam cleaning fabrics, as it can set the stain and make it more difficult to remove.
First, you need to put your dog on a schedule. This means feeding them, walking them, and giving them bathroom breaks at the same time each day. Dogs are creatures of habit, so if you have them on a schedule, it will help avoid accidents.
Dogs have several reasons for staring at their owners, like to communicate with and understand us. Some dogs stare to manipulate owners, as in with begging for food or asking to be let outside. Training and dog sports are good ways to turn focused staring behavior into a positive experience.
Peeing on the bed is common in puppies and older dogs, although with older dogs it can be a sign of a medical condition. In fact, if your dog is over a year old and has previously been house trained, peeing on the bed can be a sign of something wrong such as anxiety or fear.
Aggression in dogs commonly includes body language or threat displays such as a hard stare, growling, barking, snarling, lunging, snapping, and/or biting. Aggression can be a normal form of communication in dogs, yet the display of aggression toward a person or animal is often considered undesirable or problematic.

Q. Whenever I take my dog on walks he always barks at people and others dogs in my neighborhood. What should I do to resolve the problem
ANSWER : A. The very first thing to do is to make sure your dog is getting sufficient physical and mental exercise every day. A tired dog is a good, happy dog and one who is less likely to bark from boredom or frustration. Depending on his breed, age, and health, your dog may require several long walks as well as a good game of chasing the ball and playing with some interactive toys.

Figure out what he gets out of barking and remove it. Don’t give your dog the opportunity to continue the barking behavior.

Ignore your dog’s barking for as long as it takes him to stop. That means don’t give him attention at all while he’s barking. Your attention only rewards him for being noisy. Don’t talk to, don’t touch, or even look at him. When he finally quiets, even to take a breath, reward him with a treat. To be successful with this method, you must wait as long as it takes for him to stop barking. Yelling at him is the equivalent of barking with him.

Get your dog accustomed to whatever causes him to bark. Start with whatever makes him bark at a distance. It must be far enough away that he doesn’t bark when he sees it. Feed him lots of good treats. Move the stimulus a little closer (perhaps as little as a few inches or a few feet to start) and feed treats. If the stimulus moves out of sight, stop giving your dog treats. You want your dog to learn that the appearance of the stimulus leads to good things.

Teach your dog the ‘quiet’ command. Oddly, the first step is to teach your dog to bark on command. Give your dog the command to “speak,” wait for him to bark two or three times, and then stick a tasty treat in front of his nose. When he stops barking to sniff the treat, praise him and give him the treat. Repeat until he starts barking as soon as you say “speak.” Once your dog can reliably bark on command, teach him the “quiet” command. In a calm environment with no distractions, tell him to “speak.” When he starts barking, say “quiet” and stick a treat in front of his nose. Praise him for being quiet and give him the treat.

As in all training, always end training on a good note, even if it is just for obeying something very simple, like the ‘sit’ command. If you dog regresses in training, go back to the last thing he did successfully and reinforce that before moving on again. Keep sessions short, 15-20 minutes max, and do this several times a day.

Q. My 4 yr old male Catahoula Leopard Dog mix is a rescue. He’s become very possessive of me around larger dogs. How can I correct this behavior?
ANSWER : A. Sudden behavior changes can sometimes indicate an underlying health issue, so scheduling a checkup with your regular vet is always the first step. Once any health issues have been addressed, then you can address the behavioral ones. It is very common for dogs to become “possessive” of people or objects when around other dogs or people, and is called location guarding. Possession of objects or places can be a little easier to manage, however possession around other dogs can be treated as well. Working from a distance in a technique called BAT or Behavioral Adjustment Training may help. This technique involves your dog and another calm dog. Start off at a far distance and then move in until your dog becomes reactive or wary of the other dog. Move back a small amount and wait for your dog to become calm. If he shows calm behavior, reward with lots of praise, treats and love! If he becomes agitated or possessive, move back until he is calm, or stop the session completely and try again later. While this may take some time, it can help dogs learn that other dogs are not a threat to them or their people. Reading more information about BAT training or contacting a local trainer in your area can help with further advice and techniques!

Q. We have a 4 yr old lab-pit mix we raise from 6 weeks.If my husband tries to take hin by the collar and make him go out to pottie he growls.Problem?
ANSWER : A. This is not good behavior. Rather than take him by the collar, call him to come with you. If he’s not good about coming when called, you can work on that. Keeps treats on hand to to entice him out and reward him when he does go potty and he’ll come to look forward to it. Clicker training is another great way to teach a dog all kinds of things, from obedience to tricks.

Have treats on hand that you know he loves, then simply click and treat. He will come to associate the sound with getting a treat. Start putting distance between you so he has to come to you. Call and click and when he comes to you for that treat, treat him and give him lots of praise. Move to hiding somewhere in the house, call and click. When he comes to you reliably inside when you call, click and treat. When this behavior is consistent, move outdoors with a very long leash. Call and click, if he doesn’t respond, give a light tug on the leash. If he takes even a single step toward you, click, treat and lots of praise. Keep doing this until he comes eagerly. Next, try him off-leash in a securely fenced area. Call and click. At this point he should be responding well and coming easily to the call and click. If he does not, go back to the last step he performed reliably and work on that again until he responds well. Eventually, you can start not treating him every time, but still praise him. Gradually lessen the frequency of the treats until he comes just to the click and praise.

Keep training sessions short, ten or fifteen minutes to start, no more than 30 minutes at a time and do it a few times a day. Try not to do it any time he is overly excited so that he can pay attention to you. Always end a training session on a good note, even if it is just getting him to do something he already does well on command. And never, NEVER punish a dog when they come to you, no matter how far they’ve made you chase them, no matter how frustrated and angry you might be. That teaches your dog that coming to you is a bad thing.

Q. How do I determine how much my overweight pet should weigh?
ANSWER : A. There are many tools to determine overweight and obesity levels in pets. A new tool, morphometric measurements and body fat index, are available to accurately determine a pet’s ideal weight; this will allow an accurate determination of the amount of food a pet should receive to achieve weight loss. Feeding the correct amount will lead to greater weight loss success.

There are many weight loss food options to help pets reach their ideal weight. Your veterinarian can help make a ideal weight recommendation. Here are some tips to help your dog lose weight in a healthy and safe way:

1. Diet: Providing a healthy and well balanced diet is essential to your pet’s overall health. Finding the right food for your dog can be a challenging process. For those overweight animals many commercial dog companies offer weight loss diets, but it is important to evaluate food labels for adequate nutritional content.

You want to ensure you are not missing other essential vitamin or mineral content. Volume of food is also important and the amount of food that works for one breed of dog may not be the same for another breed of dog. Portion control as opposed to free-choice feeding can help your dog to drop a few unnecessary pounds.

There are also prescription weight loss foods designed by veterinary nutritionists, such as Hill’s r/d (http://bit.ly/1AoENSd). Some pet owners find that home cooking is the best option for helping to provide a well-balanced and realistic diet plan. There are websites such as balanceit.com that offers recipes to fit your dog’s specific needs. Consulting with your veterinarian or a veterinary nutritionist to find the appropriate diet is a great way to help your dog be as healthy as possible.

2. Exercise: Another great tactic for weight loss for your dog is exercise. Whether this is through running, walking or playing with a favorite toy all of these are wonderful types of exercise to help keep your dog at a lean and healthy weight.

For those pet owners with busy schedules utilizing professional dog walking services or playtime through dog daycare services is another option. It has been shown that those pet owners that exercise regularly with their pets generally live a healthier lifestyle.

3. Physical therapy: As animals age pet owners offer encounter their favorite canine having more difficulty walking and have a dwindling desire to play with toys. Physical therapy, specifically hydrotherapy is a wonderful way to help older and arthritic animals gain more mobility and lose weight. Hydrotherapy has been proven to have several therapeutic effects on the body including, muscle strengthening, relief of swelling, decreased joint pain, less stiffness in limbs, improved circulation, weight loss, and increased tissue healing to name a few.

4. Veterinary visit and blood work: Weight gain can also be related to underlying health concerns such as hypothyroidism or other endocrine disorders. Scheduling a veterinary evaluation and routine blood work can be another important component in increasing the longevity of your dog’s life. Conditions such as hypothyroidism that predispose dogs to gain weight can be treated with a daily medication to improve hormonal balance. If feel that your dog is unnecessarily overweight there can be an underlying health condition that needs to be addressed.

5. Healthy treats: Pet owners love the chance to reward their favorite canine companion with treats and most dogs jump at the chance to consume these delicious products. The problem is many treats, which can include commercial dog treats or table scrapes can add many unnecessary calories to your dog’s daily intake. Reading labels and making note of the calories in these treats is an important component of understanding your dog’s overall health. Treats should not exceed more than 10 percent of your pet’s daily calories. There are healthier treats that can be offered to your pet to keep calories lower yet provide a fuller sensation. A pet owner can add steamed or pureed vegetables, such as carrots, green beans or sweet potato to add more fiber and thus a fuller feeling for your dog.

Q. Why do dogs eat grass?
ANSWER : A. Some pet parents get concerned when they see their favorite canine nibbling on grass in the yard. They wonder whether it is because hunger, boredom or an indication of an underlying illness. Often the consumption of grass will result in vomiting because it irritates the stomach and gastrointestinal tract. This is an extremely common problem for dog parents. There is no one reason for why dogs exhibit these behaviors and it is very much dependent on each dog. Here are some of the reasons why our dogs choose to eat grass:

1. Nutritional Issues

Historically speaking, dogs are considered omnivores, which mean they consume a variety of both meat and plant-based food. There is some indication that dogs with a low fiber diet may choose to scavenge in the grass to fulfill this nutritional deficiency. These dogs may also find that grass has an appealing flavor and consistency. If you feel that this may be the reason for your beloved canine consuming grass then consider discussing with your veterinarian on how to incorporate more fiber into your dog’s diet.

2. Boredom

Many dogs who are not receiving adequate exercise will be become bored and search out activities to occupy their time, including eating grass. Evaluate how much exercise your dog is getting on a daily basis and consider more walks or other fun activities, such as playing fetch or tug of war.

3. Upset Stomach

There is a belief that dogs with an upset or gassy stomach will self-medicate by consuming grass. Vomiting often follows this grass eating activity eliminating the contents of the stomach or changing the gas distension within the gastrointestinal tract. However, there is not much scientific evidence to back up this theory. If you are concerned about too much gastric acid in your dog’s stomach or any other underlying medical issue that could be the reason for their grass eating, consult with your veterinarian.

Overall, grass eating is usually not toxic to your dogs unless your lawn contains chemicals, including pesticides or herbicides. Monitor your dog’s behavior along with his diet and exercise to determine if there is a reason for the inappropriate grass snacking.

Q. Why does my dog eat grass?
ANSWER : A. As another user mentioned, dogs can eat grass when they want to vomit. Sometimes, when a dog has an upset tummy, they will eat grass. If you notice your dog eating grass frantically, you can assume vomiting will shortly follow. Grass does not digest and pass normally. If your dog eats too much grass, it can cause serious issues with pooping. Your dogs poop can end up all tangled inside of her, and it can need veterinary assistance to remove it. The same goes for celery, so avoid feeding celery to your dog.

The other day my boyfriend accidentally left the laundry room door open where we were keeping the trash that was filled with cooked chicken bones. She ate one of the chicken bones lightning fast. We had to induce vomiting by feeding her some hydrogen peroxide. After we had fed her the peroxide, she immediately began frantically eating grass because her tummy was upset.

If there is something lacking in your dogs diet, it could be that your dog is eating grass to make up for it. I am sure that my dogs diet is extremely well balanced (I do not only feed her an air-dried raw food-type diet (Ziwipeak), but a wide variety of safe, healthy foods), so when she eats grass, I know that it is because she has an upset tummy.

That is why I think it is important making sure your dog has a very well balanced diet. If your dog is on a low quality kibble, your dog may be trying to let you know by eating grass (or eating poop).

Q. My 4 year old Chihuahua mix began having a series shaking/panting episodes (last 15m- 1hr) out of the blue. Vet’s tests say its not physical.
ANSWER : A. There are many causes for shaking/panting. The shaking and panting are both signs of stress, and your dog may be dealing with anxiety, or stress, related to an event that happened, or is happening. I realize you cannot answer questions on this, however, I will ask some questions that you can ask yourself. Have you recently moved? Have you ever hit or yelled at your dog? Has the weather been bad lately (storms)? Have you had any new guests stay over recently? Have you had any dogs come to your home recently? Have you had any dogs or cats in your yard recently? Was your dog frightened by something initially (a falling pot/pan; a loud bang from the washing machine; a gunshot; a backfiring car/truck; someone screaming in your home/a fight)?

If you answered yes to any of those questions, it could definitely be that. Dogs don’t typically hang on to something for very long, but if it really frightened your pup, then she/he could be feeling serious anxiety related to that specific event, and relating other events to that one.

Do not yell, or hit your dog. I’m not assuming you do, but if you do, please stop doing that right away. It could be that your dog is afraid of you specifically, and you notice the shaking/panting when you are near, because that is the only time your dog is doing it.

If you’d like to purchase a consultation with me (I know, it’s a lot to ask, but I really feel like I could help) I’d be more than happy to ask you many questions, and together we can figure out what the heck is going on here. It’s important that your dog is comfortable, and if your pup is always feeling anxious/uneasy, then his/her quality of life is in jeopardy.

Q. My puppy will be 8 weeks old tomorrow. I’ve had her for a week now, and she still isn’t responding to any training or her name. What can I do?
ANSWER : A. Try clicker training her to come when called. Clicker training is an effective way of training you dog to not only come when called, but can be used to teach a variety of tricks and tasks.

Have treats on hand that you know she loves, then simply click and treat. She will come to associate the sound with getting a treat. Start putting distance between you so she has to come to you. Call and click and when she comes to you for that treat, treat him and give her lots of praise. Move to hiding somewhere in the house, call and click. When she comes to you reliably inside when you call, click and treat. When this behavior is consistent, move outdoors with a very long leash. Call and click, if she doesn’t respond, give a light tug on the leash. If she takes even a single step toward you, click, treat and lots of praise. Keep doing this until she comes eagerly. Next, try her off-leash in a securely fenced area. Call and click. At this point she should be responding well and coming easily to the call and click. If she does not, go back to the last step she performed reliably and work on that again until she responds well. Eventually, you can start not treating her every time, but still praise her. Gradually lessen the frequency of the treats until she comes just to the click and praise.

Keep training sessions short, ten or fifteen minutes to start, no more than 30 minutes at a time and do it a few times a day. Try not to do it any time she is overly excited so that she can pay attention to you. Always end a training session on a good note, even if it is just getting him to do something she already does well on command. And never, NEVER punish a dog when they come to you, no matter how far they’ve made you chase them, no matter how frustrated and angry you might be. That teaches your dog that coming to you is a bad thing.
