How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

Yes, dogs can eat apples. Apples are an excellent source of vitamins A and C, as well as fiber for your dog. They are low in protein and fat, making them the perfect snack for senior dogs. Just be sure to remove the seeds and core first.
Yes, but in very small portions. It`s safe as long as apples are fed to your pet as treats. Always REMOVE THE SEEDS as they contain cyanide which can be lethal for your pet. Small pieces eliminate the hazard of your pet choking on them.
Dogs can eat both the skin and flesh of any variety of green apples including Granny Smith, Pippin, Crispin and Japanese Shizuka. In general, green apples are more sour than their red counterparts, a tartness that may be off-putting to some dogs.
As with any other food, your dog may be allergic to apples. In most instances, the allergy is a mere irritation, but there are instances where apple has been lethal (causing anaphylaxis) to some dogs. Some signs of an allergic reaction include: Sneezing.
Apple skins are also safe for dog consumption and can even be good for some pups who are looking to get more fiber, according to the American Kennel Club. For dogs with sensitive digestive systems, peel the apple to avoid upset stomachs.
The answer is yes. Rice is an ingredient sometimes found in commercial dog foods. Many pet owners feed white rice to their sick dog. One of the reasons white rice is the chosen grain for a dog with an upset stomach is that it`s easy to digest, quick to prepare, and low in fiber.
Ripe tomatoes are considered nontoxic to dogs and can be fed in moderation as an occasional snack. While it`s considered safe for dogs to eat red, ripe tomatoes, the plants themselves are part of the nightshade family of vegetables (which also include potatoes, bell peppers, and blueberries).
Honey is safe for dogs to eat in small quantities. It contains natural sugars and small amounts of vitamins and minerals. It is also used as a sweetener in many foods and beverages. That sweetness comes at a price, however.
To recap, potatoes are safe for most dogs in moderation. In order to be safe, potatoes need to be fully cooked. Raw potatoes and excessive amounts of potato skins are not safe for dogs because of the substances they contain.
Don`t worry—cheese is not toxic and is completely fine for most pups. However, some dogs can be lactose intolerant, meaning their body does not react well to dairy products. But even if your dog isn`t lactose intolerant, it`s still a good idea to keep their cheese consumption to a minimum.
Are carrots safe for me to feed my dog?” While some of the vegetables we love are unsafe to feed our dogs, carrots are a perfectly safe and nutritious treat for your dog.
Milk is a safe treat in small quantities. A few tablespoons of cow`s milk or goat`s milk on an occasional basis can be a nice reward for your dog. But, you should probably hold off on offering your dog an entire bowl in one sitting, as it can cause unpleasant reactions, including diarrhea, vomiting, and loose stools.
Eggs are not only a perfectly safe food source for dogs – they offer much in the way of nutritional benefits. Aside from being rich in protein, eggs are also a great source of linoleic acid, Vitamin B2 and B12 and water-soluble Vitamin A – all of which are wonderful for your dog`s skin and coat.
Eating an excess of apples can lead to your dog experiencing a bellyache or diarrhea, so always serve them in moderation. Just an apple slice or two is enough to satisfy your dog`s cravings. Puppies can also eat apples. If you haven`t given them apples before, start with a small amount, like a slice or small cube.
Dogs eating cucumbers: the FAQs

Yes, dogs can eat raw cucumber, cut into bite-sized pieces. It`s a highly hydrating and nutritious snack packed full of vitamins, minerals and fibre while being very low in calories. To start, just try a small chunk to make sure it doesn`t upset your dog`s tummy as an unfamiliar food.

All dog breeds can tolerate pasta, so long as their owners feed it to them plain and in a moderate amount. Since all types of pasta are high in carbohydrates, a small sampling can sometimes serve as an energy booster for your pet.
Ice cream is also high in sugar, which is not healthy for your pup. While lactose and sugar aren`t toxic by themselves, they could result in a period of discomfort for your best friend. Our advice: Avoid feeding your dog human treats with dairy and sugar.
Sweet potato is a safe, healthy, and natural treat for dogs, offering a range of health benefits (and a sweet flavor they`ll likely love). For example, sweet potatoes support a healthy digestive system thanks to their high dietary fiber content. They`re also low in fat and contain essential vitamins like B6, C, and A.
But can dogs eat tuna? The answer is no. You shouldn`t feed your canine companion the saltwater fish because it could lead to a number of different health problems.
The bottom line. When prepared properly, oatmeal can be a healthy addition to your dog`s diet. Be sure to only feed dogs cooked oatmeal and opt for plain varieties prepared with water instead of milk. You should also increase their intake gradually to assess your dog`s tolerance.
Dogs cannot drink tea. Caffeinated teas like green tea (made from the camellia sinensis plant), black teas like Earl Grey, white tea, or oolong tea can lead to caffeine poisoning, especially in small dogs.
The bottom line is that you should never give pizza to your dog, whether as a meal or a treat. They might experience a slight stomach upset if they`re sensitive to dairy, due to the excess fat, but overall in many cases dogs are fine.
Many veterinary nutritionists agree that corn for dogs is not a problem and in fact, can be part of a well-balanced diet. However, you should confirm that your dog is not allergic to corn prior to giving it to him.
Oranges, tangerines, and other citrus fruits are not toxic to dogs — but never feed them grapes or raisins. Oranges, tangerines, and clementines are not toxic to dogs (although not so great for cats, who may have an issue with citric acid).

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. 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. My dog doesn’t eat, what should I do?
ANSWER : A. If this is a puppy, see a veterinarian immediately. Puppies should want to eat. Common causes for anorexia in puppies include viruses (parvo is a big one), parasitism, and foreign bodies. They need immediate care – go to an emergency vet if yours isn’t open. Puppies can get low blood sugar and dehydration very quickly.

If this is an adult dog and you observe other concerning signs, such as diarrhea or decreased energy, you should see a veterinarian.

If the dog seems otherwise bright and stable, try offering different types of food: wet food, canned tripe, or cooked chicken and rice. Some dogs will go for canned baby food: chicken, turkey, or beef as the main ingredient. Make sure there are no garlic or onions in the ingredients!

Causes of anorexia in adult dogs can range from less serious to severe. Younger dogs are more likely to get into trouble- they tend to eat things they shouldn’t, and can get foreign bodies from eating things like socks, or stomach upset from getting in the trash. Any dog may stop eating due to stress, or just being a picky eater. Middle aged dogs can stop eating when they’re stressed and also have Addison’s disease, which can be fatal. Older dogs tend to stop eating when they develop cancer or renal disease.

There is no one-size-fits-all recipe to know when the right time is to take your dog to the vet. The moral of this story is, if it’s not getting better, your pup feels bad, or you’re worried – go see the vet!

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. For more information on the benefits of hydrotherapy:

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. 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. Why does my dog eat grass? He throws up afterwards!
ANSWER : A. There is much debate over why dogs eat grass and then vomit afterwards. One theory is that the dog may have an upset stomach, and so eats the grass blades which then irritate the digestive system and causing vomiting to happen. Another theory is that the dogs are eating grass to mimic a “lost nutrient” of their ancestors found usually by hunting and then eating the contents of the stomachs of herbivores. A third theory is that dogs just do it because to them, it’s fun and they can.

If your dog has been vomiting a lot recently, either related to or unrelated to eating grass, then it is always a good idea to schedule a wellness exam with your vet to make sure there are not any issues causing illness. Grass, especially in areas where livestock may graze can also be a host for parasite eggs, which can in turn infect your dog with an internal parasite (and thus cause vomiting and diarrhea).

If your dog is not eating at all, this is more concerning and points further to some digestive upset causing his or her symptoms. Making an appointment with your vet as well as bringing in a sample of his or her stool is best for helping your pet feel better.

Q. Rescued a dog almost two weeks ago, and now that her kennel cough is gone her personality shines!! No previous training, how should I start?
ANSWER : A. POST FOUR:

After your dog is familiar with the behavior you lured from scratch, and taught to your dog, you can start to use the “no-reward marker” I talked about. What you do is ask the dog to perform the behavior, and if the dog does not perform the behavior, you simply say your no-reward marker (choose one: eh-eh, hey, uh-oh, oops) show them the treat, put it behind your back, and BRIEFLY ignore your dog. Just turn your back for a second or two, before turning back to your dog and saying, “let’s try that again.” When you’re ready to start over with your dog, make sure you move around. If you are repeating the same cue while in the same position, while your dog is in the same position, you are likely to receive the same results. The more you move around, and start fresh, the better your chances are of having your dog listen to your cue the second time around. BIG rewards when they dog it successfully! Lots of praise and treats.

My no-reward marker is “hey.” When my dog does something wrong I say, “hey” and she immediately understands that she needs to offer a different behavior. This is clear to her. I don’t have to say it in a mean way, I simply say, “hey” in a normal tone of voice and she understands what the word means.

Once you’ve built up that connection and communication with your new dog, you can work on all kinds of fun behaviors! I personally enjoy the more zen-like behaviors: https://www.youtube.com/watch?v=ruy9UMcuGh8

I like to teach my dog fun tricks that offer her a “job” to do of sorts like object retrieval: https://www.youtube.com/watch?v=I4iertZSva8

(object retrieval training completed; what it looks like: https://www.youtube.com/watch?v=jx0Dml28FGY)

Scent-games are fun too! Very confidence building. Hide a REALLY smelly treat in a box, and place that box in a line of boxes. Let your dog go in the room while saying something like “search!” or “find it!” and watch them hunt for that smelly treat! Lots of rewards when they find it!

Q. My Beagle listens to me, but cries & whines when I’m gone & doesn’t listen to my parents. I adopted him just a couple days ago. Any tips for my folks?
ANSWER : A. I really highly doubt that your Beagle listens to you and has formed a connection with you in just a couple of days. It takes months to build up any kind of serious connection with your dog. You need to work on communication with your dog through training them to understand different cues. For instance the Leave-It cue: https://www.youtube.com/watch?v=R1TS5nA7z5Q

You have to work on bonding with your dog through mental stimulation. Training is very important. Luring each new behavior from scratch, and training using treats is how you form a strong bond with your new dog. No scolding is ever necessary… work on being calm, and positive, all the time.

If your dog is crying/whining when you leave, this may be separation anxiety. You’re going to have to separation train this dog from scratch. This dog needs to learn that separation can be a good thing! Tell your “folks” to NOT scold the dog when he is crying/whining after you leave, because that will make your dog MORE anxious when you leave next time. Your dog will be dwelling on the negative if your parents fuel your dogs negative feelings towards you leaving. FUN things should happen when you leave. Your parents should pull out the treats and start doing some basic obedience training with your dog. Your parents should stuff a Kong filled with awesome treats (peanut butter) and give it to him so he feels happy when you leave.

I have some excellent separation anxiety exercises you can work on. If you’d like, you can purchase a consultation with me, and I will go over how to separation train from scratch. It will make your dog comfortable being alone, guaranteed.
