Experienced and professional animal trainer provide their insights in answering this question :
A. Licking the feet and legs can be caused by a number of things in dogs including allergies, illness or even stress behaviors. Allergies are the most common in dogs, with yeast infections coming in second. Allergies can cause the area to become red and itching, making your dog want to lick and chew on them. Over time, the area may become stained from saliva, especially in lighter or white-coated dogs. Yeast infections are also common between the toes, and may cause a smelly “corn chip” smell to appear near your dog’s feet. Again, dogs will attempt to lick and chew to relieve the itch. Keeping the feet clean and dry can help relieve both allergies and infections and pet wipes or a baby wipe of all paws when your dog comes in from outdoors may also help. Keeping your dog from licking the space with either dog booties or an Elizabethan collar is also good as it will prevent secondary infection and staining of the paws and legs. If your dog is determined to keep licking and keeping the feet clean and dry do not help, then your vet can help by providing a medication to treat any infection or provide relief of allergies.

How to Identify Common Pet Problems ?

When dogs lick their paws excessively, a build-up of porphyrins from the saliva turns the fur around the area pink or rusty red. Over time, the stains can turn a darker brown. While the staining is only unsightly, excessive licking is often a sign of an underlying medical or behavioral issue.
Dogs with white or light fur that repetitively lick their paws will often get orange-pink-brown staining to their paws. This is a sure sign they`ve been licking at them more than necessary. The staining is from porphyrin, which is present in canine saliva.
Hyperpigmentation is a darkening and thickening of the skin seen in dogs. It is not a specific disease but a reaction of a dog`s body to certain conditions. Hyperpigmentation appears as light-brown-to-black, velvety, rough areas of thickened, often hairless skin. The usual sites are in the legs and groin area.
Simply make a paste with water and baking soda and apply it to the affected areas. Let it sit for a few minutes before rinsing it off. You may need to repeat this process a few times to see results. There are also a number of commercial dog shampoos on the market that are specifically designed to remove brown stains.
Symptoms of a yeast infection include red, itchy skin, discolouration, and a sweet, musty odour. If a yeast infection is present in the paws (one of the most common areas), the paws will become red and itchy, and there may even be a brown discharge present in the nail beds.
While it is never a good idea to feed your dogs baking soda, accidental ingestion of small amounts should prove harmless. However, as with all things, it can get toxic if they consume large quantities.
“The most common cause of paw licking is generally environmental allergies, also called atopic dermatitis,” Dr. Flynn says. “Other causes of licking paws can include ectopic parasites such as fleas or mites, referred pain from arthritis — licking the feet or limbs since they can`t reach the painful joint.”
The characteristic reddish-brown color of dog tear stains is caused by an iron-containing dye molecule called porphyrin. When the body breaks down red blood cells, porphyrin is released. This molecule is excreted in the bile, tears, saliva, and urine of dogs.
The white vinegar remedy works best if you apply it to itchy areas 2-3 times daily. Unfortunately, some dogs dislike being sprayed with a spray bottle. If your dog doesn`t like being sprayed, you can rub the mixture on with a cloth or cotton ball. Simply use whichever method is least stressful for your dog.
How do I Treat My Dog`s Irritated Paws? ACV will soothe the irritation on paws that are infected by bacteria due to excessive licking and scratching. Soak the paws of your pooch in two-part water to one part Apple Cider Vinegar bath for 5 minutes. Just pat dry the paws and do not rinse them.
Baking soda works to remove odors from your dog`s skin and fur. The baking soda paste should be applied before the shampoo and can be washed off as you lather homemade dog shampoo and then rinse both items off the dog with warm water. In a big spray bottle, put 2 cups of warm water with 1/2 cup of white vinegar.
Age is one of the most common reasons for pets going gray. This is a very similar process to the one we see in humans as we age. However, unlike humans, dogs don`t tend to go gray throughout their entire coat. The majority of graying will happen around the muzzle and face.
Brown fur staining is primarily caused by an infection with the yeast Malassezia. This is the yeast that is responsible for skin and ear infections in dogs.
Mix vinegar with warm water in a clean spray bottle. Spray generously over stain. Over top of the sprayed stain, spread a thin layer of baking soda. Within an hour (or longer for set-in stains), the baking soda will absorb the urine or fecal residue and remove the stain.
Skin and Paws

Topical ingredients that are effective in treating yeast include chlorhexidine, miconazole, and ketoconazole. In difficult-to-treat or severe cases, oral antifungal medications are used. Oral antifungal medications used in dogs include fluconazole, terbinafine, ketoconazole, and itraconazole.

The paws are a common site for a yeast infection in a dog. If your dog is licking or chewing at their paws, they may have some pain, discomfort or itching there. Yeast infections are one of many reasons why a dog`s paws might be irritated, and constant licking can cause more inflammation and discomfort.
When some dogs eat ingredients such as chicken, wheat, corn or other individual items, ingestion will trigger an allergic reaction that can alter the natural flora and allow an unnatural growth of yeast.
Recipe 4: Baking soda

It also softens the skin and reduces itchiness. Add 1-2 tablespoons of baking soda to about 5l (1 gallon) of water. Dunk your dog`s feet in the bucket straight after your walk and keep the feet in the remedy for about a minute or two.

Dogs can have distilled white vinegar or apple cider vinegar (ACV) as long as you use it in moderation. Serve your dog one tablespoon of diluted vinegar in their water bowl or let it soak into their kibble. Keep in mind there is always the possibility your specific dog might have an allergy or intolerance to vinegar.
Signs of an infection in the paws include licking and chewing the paws, redness, swelling, pain, itching, and drainage. Typically, the skin between the toes and other skin folds is affected with itching, redness, and greasy discharge. Sometimes, brown discoloration of the nails.
White dogs can be more prone to allergies. Dogs with white coats experience mo sun damage to their skin and therefore are at a higher risk of developing skin cancers that res t from sun exposure. There are many causes of skin issues in dogs.
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.
The common causes for this abnormal grooming behavior by your dog might be allergies, skin irritation, fear, and pain. For instance, orthopedic problems like hip dysplasia can be excruciating for your dog and cause him to bite his paw pads. Thus, it`s essential to treat the underlying health concerns.

Q. My dog licks his feet and legs and they are turning brown. He is a white dog. Can you help?
ANSWER : A. Licking the feet and legs can be caused by a number of things in dogs including allergies, illness or even stress behaviors. Allergies are the most common in dogs, with yeast infections coming in second. Allergies can cause the area to become red and itching, making your dog want to lick and chew on them.

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 dog has no fleas, but is scratching and licking continually. He has been through a round of prednisone and it hasn’t helped. What can I do?
ANSWER : A. Itching can be caused by more than just external parasites, and if your dog is already on a flea medication, then it is possibly not the case. Itching can indicate anything from allergies to even minor skin infections causing problems. If your dog has been treated with prednisone (a steroid that inhibits the immune system) and it did not help, then looking at other options may help.

Food allergies are very common in dogs and can present with itching and licking all over the body rather than on just one spot. Common food allergens include ingredients such as wheat, corn and soy products, however dogs can be allergic to almost anything! Starting a food trial of an allergen-friendly diet from your vet or pet store that avoids these common ingredients may help. The food should be switched over a period of 7-9 days and then given about a month to decide if it is helping.

Small skin infections or yeast in the skin can also cause itching, however this itching is often more specific to a certain area of the body (such as the toes, or base of the tail). Your vet can perform a skin scraping of the area to be cultured at a lab to look for any yeast or bacteria. If they are present, a medication given either orally or placed on the affected area can clear up the infection.

In some cases, licking and chewing can actually be due to a boredom or anxiety behavior. Dogs may lick one spot obsessively to the point of creating sores or wounds in the area. Stopping your dog from licking and chewing either through the use of dog booties, no lick strips, T-shirts or even Elizabethan collars can break the habit and give the area time to heal. Licking and chewing can also cause the spread of bacterial infections so should be deterred even if not behaviorally caused.

Q. I’m almost positive my dog is afraid of the dark! Every time I turn off the light she starts crying! Is there a way I can teach her not to be afraid
ANSWER : A. You may need to take things very slowly. First off, you should consider using a night light in the room you have your dog in. I have a night light in my room for my dog, even though I don’t feel the need to use one. You should have a handful of treats, and toss several of them to your dog. While your dog is eating the treats, shut off the light, and then turn it back on and toss several more treats to your dog. While your dog is eating the treats, turn off the light and count to three, then turn it back on. Toss several more treats to your dog, turn off the light and count to five. Turn the light back on, toss several more treats to your dog, shut off the light, count to four. Turn on the light, toss treats, turn off light, count to eight. Turn on light, toss treats, turn off light, count to five. The key is to randomly increase and decrease the amount of time the pup is in the dark. Work on it slowly, slowly build duration. Do not expect it to happen all in one session.

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. 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. Why does my dog keep licking her butt alot? We can’t take her to the vet. But, after the bath, she seem fine and not lick her butt alot.
ANSWER : A. I would ask the vet (or groomer who gives the bath) if they are expressing your dog’s anal glands during the bath. This is a very common thing for them to do and it would explain why your dog is so comfortable after a bath. It would also explain why your dog licks her bum so often! Dog’s have these bothersome glands that are located right next to their anus called anal glands. These glands fill up every week or two with fluid (in some cases, very thick fluid) and many dogs have a hard time expressing this fluid on their own. This causes them a great deal of discomfort and in turn causes them to lick their bum! Some dogs will even scoot their bum on the carpet in an effort to empty the glands. Your vet (or your groomer in this case) can help you and your dog out by emptying these glands out on a regular basis and keeping your dog comfortable.
