Experienced and professional animal trainer provide their insights in answering this question :
A. Yes I would recommend a vet visit because he is having intermittent (off and on) limping it could mean he has a muscle sprain or a torn ligament in the knee. They can look the same so it is important to have your vet examine and perform a lameness exam to tell which is more likely so that proper treatment is implemented to help avoid further injury to that leg and also the other leg he most definitely is bearing more weight on to take the pressure off the injured one.

How to Identify Common Pet Problems ?

Dogs can get muscle and joint soreness just like their human counterparts, especially after a session of more than usual exercise. Usually, this kind of dog limping will only be mild, and they will recover from their soreness within a few days.
If your dog has pulled a muscle you may notice him limping or walking on 3 legs. He may hold his leg up when he is standing still or sitting. You may also hear him whine or cry and may go off his food if it is very sore.
Sudden limping is the type of limping that develops instantaneously. It`s usually due to some sort of injury or trauma. If you notice that your dog has started limping suddenly, you should take them to the vet right away to find out the cause and what can be done to help it.
A simple rule of thumb to help determine the severity of the injury is that most dogs will not walk on a broken leg, torn ligament, or dislocated joint. A good exam requires two people: one to examine the leg and one to restrain the dog. Dogs that are in pain may bite, even people they love so be cautious.
Sometimes limping will go away on its own, especially if you provide some at-home support like a brace. Other times limping may be a sign of a more serious injury or condition that will require veterinary intervention.
If the limp doesn`t resolve itself within 48 hours, becomes worse, or if your pup is whining or yelping, it`s time to call your vet to book an examination for your pet. Your veterinarian is best equipped to determine the cause and severity of your dog`s pain.
Osteoarthritis, hip dysplasia, elbow dysplasia, patellar luxation, ligament disease, intervertebral disk disease, and osteochondritis dissecans (OCD) all can cause limping on any of the affected limbs.
Things to look for when a muscle is pulled are muscle spasms, weakness, cramping, and immobility, as well as pain, bruising, and swelling.
Dogs can have pulled muscles just like humans, and it can be heartbreaking to watch your dog walk around with a limp. The muscles most often injured are those in a dog`s front or hind legs and the most common symptom is a limp.
Generally, if your dog`s limp isn`t severe, you can just monitor your pup`s progress at home over 24-48 hours, watching for more symptoms or to see if the limp becomes more pronounced. Most of the time it`s best to err on the side of caution and schedule an appointment with your vet.
If your pup is still limping after a day, take them to the vet. “I can`t emphasize enough that lameness is a sign of pain,” Dr. Devitt says. Limping isn`t a typical behavior (even after a long day at the park) and should be recognized as your pup needing care.
Dogs can limp for many reasons. Active or heavy pets can twist and strain things just like humans do. Any dog can jump or run and twist or turn a joint in a manner that causes temporary discomfort. Most injuries caused by such things are short-lived.
In most cases, it`s better to be safe than sorry, and scheduling an appointment with your vet may help both you and your dog to feel better. If the limp doesn`t begin to resolve itself, is becoming worse, or is accompanied with whining or yelping, it`s time to call your vet or visit your nearest emergency vet.
It`s always best to seek veterinary care sooner rather than later. My dog is limping but not crying – what should I do? A dog limping but not crying or showing other signs of pain should still be taken seriously.
This is another question to ask yourself before knowing when to let your dog go. Most often, weakness and inability to move freely are clear signs that the animal needs urgent medical help or has declined to the point that it`s time to consider euthanasia or putting your dog to sleep.
There is lameness after heavy exercise, a waddling gait, and difficulty rising after laying down. The signs may come on suddenly, or you could notice a gradual decline in your pet`s usual activity. Pain may be evident when handling the hips.
The definitive diagnosis usually comes with a radiograph or X-ray. Your veterinarian will take radiographs of your dog`s hips to determine the degree and severity of the hip dysplasia, which will help determine the best course of treatment for your dog.
Dogs who have hip dysplasia may sway back and forth when they walk. They may also have a bunny-hopping gait or may stand flat on their back feet. All of these potential gait issues are related to the pain they feel when they suffer from hip dysplasia.
Massage the Muscle

Massaging the sore area of your dog can help speed up recovery, lower pain and discomfort, improve mobility, and help your dog use their leg more comfortably. There are many resources on the internet to help teach you how to massage your dog, or you can ask your vet.

Instead of attempting to self-diagnose your dogs injury, the only way to tell whether a dog has a sprain or a broken leg is to take the dog for a complete visual exam by a veterinarian. Your veterinarian can then determine if x-rays are needed.
Many sprains and strains can be treated simply with rest and nonsteroidal anti-inflammatory medications (NSAIDs) such as Rimadyl, Metacam, or Galliprant. If rest is recommended, it is important to keep your dog`s activity level as low as possible. Leash walk only when taking them outside to eliminate.
While a sprain is more serious than a simple strain, most dogs make a full recovery from a sprained leg. The biggest challenge most pet parents face is convincing their active and energetic canine companions to take it easy for the roughly six weeks it takes for a sprain to heal.
What are the typical signs of pain in dogs? General behaviour: Shaking, flattened ears, low posture, aggression, grumpy temperament, panting or crying, excessive licking or scratching a specific area, reluctant to play, interact or exercise, lameness (limping), stiffness after rest, loss of appetite.

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. 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. Husband shamed dog for having an accident inside, and now she won’t poop when he takes her out. Can we fix this? He realizes he erred
ANSWER : A. Good on your husband for realizing that scolding is not the way to potty train! Hopefully these tips can help both him and your pup get back on the right track and make pottying outside successful.

If your dog is still a puppy, that is good news as you may be able to more easily time your potty outings with your dog’s schedule. Even if your dog is older, this schedule may help. Dogs generally have to go potty about 15 minutes after eating, drinking, waking up or playing. Knowing this, get your husband to start taking out your puppy at these key times, so puppy gets used to going out with him, and the urge to potty may be higher than any fear to go. If the potty is successful, have your husband reward the dog with a favorite treat! For bowel movements, dogs may take a little more time, and you may have to stand outside for a while (sometimes even 10 minutes) to give your dog a chance to go. If she doesn’t go, take her back inside and play some, then try again in about 15 minutes. Again, a success equals a treat which most dogs will like right away!

For any indoor potty accidents that occurred, an enzymatic cleaner is great for cleaning up urine and stool. Not only does it remove the stain and smell, but it breaks down the enzymes in the urine and stool your dog can smell, which may deter her from going potty there again.

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 dog was playing fech and started limping and walking on 3 legs some times he walks on all 4 legs. Do I need to go to a vet?
ANSWER : A. Yes I would recommend a vet visit because he is having intermittent (off and on) limping it could mean he has a muscle sprain or a torn ligament in the knee. They can look the same so it is important to have your vet examine and perform a lameness exam to tell which is more likely so that proper treatment is implemented to help avoid further injury to that leg and also the other leg he most definitely is bearing more weight on to take the pressure off the injured one.

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.

Q. How can I train my 4 month old puppy to sit?
ANSWER : A. Training basic commands such as sit is very easy using a positive reinforcement method and does not require any more materials than a place to sit and some very yummy treats! When beginning to teach your dog new tricks, starting off in a distraction free area (such as a quiet room in the house) is best. The training can then expand to more distracting places once your dog has the hang of things.

Start by showing your dog a tasty treat and placing it over his or her nose. When they begin to sniff at the treat, gently move the treat backward. Most dogs will follow the treat with their head, and the backward motion will cause their back ends to sit down! Once your dog sits, reward with the treat and some praise. If your dog tends to walk backwards instead of sit, doing this technique against a wall will prevent your dog from walking backward and encourage sitting.

Once your dog has done this a few times, begin to add the word “sit” every time you put the treat above your dog’s head. Only say the word once, and then continue with the luring motion. Your dog will begin to associate the word with the action after several tries! After this, you can begin to attempt to offer the word “sit” once, and if your dog does so, reward with a treat and praise! If your dog forgets, or appears bored, stop training and try again at a later time- most puppies only have an attention span of a few minutes at most!

Q. What can I do to stop my dog from barking at people and front doors?
ANSWER : A. Ignore your dog’s barking for as long as it takes him to stop. This means don’t give him any attention at all while he’s barking. Your attention only rewards him for being noisy. Don’t talk to him, don’t touch him, and don’t even look at him. When he finally quiets down, 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. If he barks for an hour and you finally get so frustrated that you yell at him to be quiet, the next time he’ll probably bark for an hour and a half. Dogs learns that if they bark long enough you’ll give them attention.

Teach your dog the ‘quiet’ command. It may sound nonsensical, but 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.

When your dog starts barking, ask him to do something that’s incompatible with barking. Teach your dog to react to barking stimuli with something that inhibits him from barking, such as lying down in his bed.

Make sure your dog is getting sufficient physical and mental exercise every day. A tired dog is a good 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 fetch and playing with interactive toys.
