How to Identify Common Pet Problems ?

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

A dog losing hair on their tail may be the result of a condition called atopy (environmental allergies) or food allergies. Dogs with these types of allergies may benefit from a therapeutic food and your veterinarian can provide this specific nutritional recommendation when needed.
Many external parasites can cause hair loss and itchiness, not just on the tail, but all over the body. Fleas, demodectic, and sarcoptic mange are among the most common culprits. Fleas are dangerous and a nuisance, but based on where you live, they can be seasonal issues.
Congenital hypotrichosis is a condition where dogs experience the loss of their hair either at birth or just a few months old. This is due to a problem in the development of their hair follicles or their not having some or all of the follicles where hair will typically grow from.
Excessive shedding can be caused by stress, poor nutrition, pregnancy, lactation or another underlying medical condition. If you think your dog is shedding more than normal or if he is developing bald patches, schedule an appointment with your vet.
Hair loss from infection or infestation can be caused by ringworm fungus, mange mites, fleas, parasites, ticks, and bacteria. In fact, fleas and mites are oftentimes the most common culprits behind hair loss and allergic reactions.
Symptoms of Demodectic Mange

In localized cases, it shows up as patches of hair loss and red, scaling skin. In generalized cases, the entire body may be covered with redness, infections, scaling, swelling, and crusts. Often the dog loses most, if not all, hair.

Itchy skin and hair loss are two of the biggest indicators that your dog has an allergy. They could be allergic to certain ingredients in their food or environmental factors like pollen or dust mites. Your vet can conduct tests to determine whether your dog has food or environmental allergies.
Puppies lose their puppy coats between 4-to-6 months of age, although this time frame varies widely from breed to breed and can start at 12 weeks or wait until they`re one year old. You might not notice your puppy shedding, especially if she is a shorthaired breed, or the change could be dramatic.
In general, most puppies will go through seasonal shedding in the spring and fall. You might think temperature changes cause the shedding, but it`s actually exposure to light. More light exposure means more hair loss. So, if you have a mostly indoor dog, expect the artificial light to cause some more shedding.
Ticks, mites, fleas, lice, ticks and worms are all parasites that can cause dog hair loss. They all cause discomfort for your dog and if not treated, can cause your dog to lose hair. If you think your dog has any of these parasites, consult your vet to find the right treatment.
Stress. In some cases, a stressful circumstance can cause a dog to lose hair. It could be moving house or the departure of a close companion. When the pet is calmer, one could expect its fur to regrow.
Dehydration can lead to increased hair loss, so make sure your doggo drinks enough fresh water.
Anxiety and boredom commonly cause a dog to keep licking their paws. The repetitive motion is soothing for dogs. The area may show hair loss with thickened, raised skin, or a lick granuloma. A prescription medication that can treat lick granulomas is Synotic with additional banamine.
Thyroid medication and hormone therapy can reverse hair loss in hormonal and endocrine disorders. Vitamin E, Vitamin A and fish oil supplements may be recommended for pets with certain conditions or a predisposition to dry skin or skin infections.
Most dogs shed hair, especially during the hot summer months, but a dog losing hair in massive amounts or with bald spots could mean something more serious such as allergies, hormonal imbalance, mites, trauma or infection.
The early signs of mange include alopecia (hair loss); scaling or crusting of the skin; papules or bumps on the skin; mild, moderate, or severe itching; and self-induced excoriations (wounds).
Mites that cause scabies and mange can spread easily. Physical contact and sharing clothes or bed linens with someone who has mange can cause the infection. Mites can live for days on animals or textiles. You may even get scabies or another form of mange from sexual contact.
Does mange go away on its own? Demodectic mange can resolve on its own in mild cases. It usually takes 1-2 months for mild, localized infections to resolve spontaneously.
Vitamin D deficiency in dogs can cause heart failure, muscle aches, muscle weakness, bone pain, hair loss, fatigue, poor wound healing, and/or lethargy. The most significant signs of vitamin D deficiency in dogs are those of heart failure.
The symptoms of B12 deficiency are not always easy to spot. The most common is weight loss, which can easily be mistaken for other health disorders. Some of the common symptoms would include reduced appetite, a dull hair coat, diarrhea, lethargy, mental dullness and neurological problems.
Yes. Eggs are good for dogs to eat. Of course, they are rich in protein, but aside from that eggs are also a good source of linoleic acid and fat-soluble vitamins like Vitamin A. All of these are wonderful for a dog`s skin and coat,” says Dempsey.
Generally, it is recommended to bathe dogs every 2-3 months, or as needed if they become excessively dirty or develop skin issues. Bathing too frequently can strip their coat of natural oils and cause skin irritation.
Unhealthy coat`s appearance: A dog with an unhealthy coat will have dry and brittle hair with lots of loose hair in the coat. The coat itself may also be greasy or have a dusty appearance and include bald spots and an unpleasant oily smell.
With most types of alopecia, the dog`s fur loss is temporary and hair growth resumes once the root cause is treated. However, inherited forms of alopecia are sometimes permanent or recurring conditions.

Q. Hybrid wolf dog is losing a lot of hair around butt, we just got a new puppy and I’m worried that could be the reason…any thoughts?
ANSWER : A. He may have fleas, or mites or anal sac problems and therefore licks or scratches the are a a lot which can cause hair loss. The only way the new puppy could be the reason is if the puppy licks the other dog’s butt a lot and pulls out the hair. Better take your wolf hybrid to a veterinarian for an exam.

Q. How do I get my dog to stop chewing on things? I kennel her when I leave for a few hours, but I can’t go to the mailbox without her eating something.
ANSWER : A. If she’s young, then this is just normal puppy behavior. Don’t worry about it. The thing about puppies is, they explore using their mouths. If your puppy grabs a coat hanger, or a slipper, you should roll up a newspaper, and smack yourself on the head with it for leaving those things out.. your puppy is going to explore things, that’s normal! It is 100% up to YOU to keep those things away from your puppy when your puppy is unsupervised… even for just a moment.

Remember to never scold your puppy for grabbing these things. They are just curious little cuties, and they don’t chew things up to bother us.. Dogs do not have intentional thought, so they aren’t ever doing anything ON PURPOSE to us.. The most important thing you can do when your puppy is chewing something you don’t want her to be chewing is TRADE her the inappropriate item with a toy of hers, so she understands “no honey, that isn’t what puppies chew on… THIS is what puppies chew on!” and then begin playing with her using her toy to show her that TOYS ARE FUN.. Way more fun than a boring ol’ coat hanger.

Another helpful thing you can do is have two bags of toys. In each bag is many different kinds of toys. Lots of chew toys, lots of soft squeaky toys, lots of rope-type toys, a bunch of balls.. All kinds of things! For one week you have bag#1’s toys out for your puppy to play with.. At the end of the one week, you collect those toys, and you bring out bag#2! The toys will be more interesting/feel like new to your puppy, which will in-turn, make her chew less inappropriate things. Her toys are too fun to care about that dumb Wii-mote that you left laying around.

Hope this helps!

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. 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. My Bulldog puppy growls, barks and even tries to bite me when I say “no” to him. What can I do?
ANSWER : A. First, avoid scolding him and acting aggressively towards him if you don’t want him to be acting aggressively towards you. There are other methods you can use to communicate to your dog that you don’t want him to continue doing what he is doing. I recommend you stop telling him “no”, scolding him, or raising your voice at him. Everything coming from you should be 100% positive and 100% calm.

Try to figure out ways to clearly communicate what you want to your dog. If you want your dog to leave something or someone alone, I strongly suggest teaching your dog commands like “leave it”. Here is a link to a video in which I explain how to do it:

www.youtube.com/watch?v=R1TS5nA7z5Q

Another thing I suggest you use is a no-reward marker. This clearly communicates when your dog has done something wrong. No-reward markers have to be introduced during your training sessions. You should be doing at least three training sessions per day, that are something like 3-10 minutes long (working on different things each training session). If you are teaching your dog something BRAND NEW, do not use the no-reward marker, as you do not want to discourage your dog from performing behaviors for you. Use the no-reward marker for known behaviors only. Here is another helpful video about this:

www.youtube.com/watch?v=sdU5a6fXKlg

Lure each new behavior (as shown in the video) using high value treats. Let’s say you’re working on “down” which is a behavior your dog knows fairly well. Present the treat to your dog. Ask your dog to “down” (only ask once). If he does not go “down” immediately, say, “uh-oh” or “eh-eh” in a gentle tone, and then place the treat behind your back. This communicates to your dog that they did something to make the treat go away.

After you place the treat behind your back to show your pup “that was wrong” you need to communicate to your pup “let’s try again” by getting your pup to walk around for a second, and then start the behavior all over again. If your puppy is very young, chances are you haven’t taught him a solid “down” behavior yet. So, as I said, do not use this method until you have lured each new behavior as shown in the video.

This is the order in which you should teach behaviors: Lure using a high value treat as shown in the video. After a few successful food lures, lure with an empty hand. If the pup is successful with the empty hand lure, reward with lots of treats. If the pup is unsuccessful, then go back to food-luring a couple more times. After a few successful empty-hand lures, you can begin to add the cue. Say “sit”, then lure with an empty hand, and then reward. Once your pup understands the cue, begin to work on the no-reward marker.

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. 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!
