Experienced and professional animal trainer provide their insights in answering this question :
A. Sounds like your dog isn’t feeling well and may have eaten something they’re not supposed to. It would help to try and figure out what the dog could of eaten or what changed in the dog’s routine. I would recommend seeing a vet. Monitor for lack of appetite and no interesting in drinking. If vomiting with diarrhea happens go to the vet or emergency vet. Not nothing what the dog could of done or eaten makes the situation a little more tricky because we can’t tell how serious it could be. If it was something toxic or something that won’t pass in a bowel movement it’s better to take the dog into the vet now.

How to Identify Common Pet Problems ?

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

If your dog is throwing up, but still acting otherwise normal, it`s possible that your pet has either chronic gastritis (inflammation of the stomach) or food indiscretion. Food indiscretion in dogs is very common when they get so excited about eating that they eat too fast or too much, and some of it comes back out.
Yellow vomit is very common when a dog has an empty stomach, and the yellow color that you see is due to bile secretions. This occurs most commonly in the middle of the night or early morning hours. It can be caused by acid buildup, reflux, or any other systemic condition that causes nausea on an empty stomach.
Slimy Vomit

Vomiting mucus is your dog`s way of getting relief from nausea. Fatty foods like table scraps can result in inflammation of the pancreas and cause vomiting. Inflammatory bowel disease, intestinal blockage, and upper respiratory infection are also potential reasons for slimy vomit.

My dog`s vomit is thick and gooey…

It could be mucous, which is often a sign of regurgitation — a distinct reaction separate from vomiting. Regurgitation often occurs when a dog simply doesn`t digest a food item, and may appear like a simple burp after being rejected by their esophagus.

Your puppy will vomit and have diarrhea if canine parvovirus is present in their system. Vomit may be clear or a yellow or brown color, and diarrhea will often contain blood and be a light yellow or mustard colored hue.
Green or yellow vomit, also known as bile, is produced by the liver and stored in the gallbladder. The release of bile occurs when an individual is vomiting on an empty stomach or is suffering from bile reflux.
Prompt attention from a veterinarian should be sought if your dog vomits multiple times in one day or for more than one day in a row. In addition, you should seek veterinary attention if your dog shows the following symptoms accompanied by vomiting: Loss of appetite. Change in frequency of urination.
Typically, black vomit could be a sign of mud or dirt that your dog digested accidently while they were playing. If black vomit has a similar appearance to coffee granules, look at it closely; if you find that it`s actually a very, very dark red, this may be a sign of a stomach ulcer or an undigested toxin.
Some of the signs of parvovirus include lethargy; loss of appetite; abdominal pain and bloating; fever or low body temperature (hypothermia); vomiting; and severe, often bloody, diarrhea. Persistent vomiting and diarrhea can cause rapid dehydration, and damage to the intestines and immune system can cause septic shock.
A dog throwing up mucus occasionally may not be a cause for concern. However, if your dog is throwing up mucus frequently, you should take them to the vet. You should also take your dog to the vet for vomiting if they are very young or very old or have other illnesses.
The vomiting of yellow mucus may be an indication that there is bile in the dog`s vomit. Bile is an alkaline fluid, which helps with digestion. It breaks down lipids (fats) into smaller particles, which the body is then able to digest.
Early Symptoms of Intestinal Blockage in Dogs

Some dogs may be immediately put off by food with others just not eating as much. Some of that food may make its way through, or a dog may always vomit a meal back up, even a couple of hours later.

Most dogs with a GI obstruction have severe abdominal pain as well as a lack of appetite. A classic sign of pain is the bowing down position. Your dog may not want to be touched on the tummy. Or she may groan and be tense and wide eyed when you touch her there.
The clinical signs of more advanced kidney failure include loss of appetite, lethargy, vomiting, diarrhea, and very bad breath. Occasionally, ulcers will be found in the mouth.
Gastritis is defined as inflammation of the lining of the stomach. It may occur as a short episode (acute) or have a long duration (chronic) and may be associated with underlying conditions that are more serious.
Clear, slimy or foamy vomit that`s tinged with yellow indicates your dog`s stomach was empty at the time vomiting occurred (the foam comes from mucus that`s normally present in the stomach plus saliva, while the yellow is bile from the small intestine).
One of the most common ways to help a dog that is recovering from vomiting is to feed them a bland diet (usually white rice, sweet potato, boiled chicken or white fish). If your dog has been treated by your vet then they may also give your dog a specially prescribed diet and some medication to help them feel less sick.
Dark vomit often comes from bleeding in the stomach. It can be from several causes: A gastric ulcer or gastritis. Inflammation of the stomach lining from things like nonsteroidal antiinflammatory drugs (NSAIDs like Advil), infections, and smoking.
Yellow or green vomit can emerge with a flu virus or fasting, while black vomit is indicative of a more serious digestive problem that is causing internal bleeding. Vomit is a normal response to the presence of foreign substances or microorganisms in the body, however it can be a sign of a gastric illness.
In cases where the cause is thought to be dietary indiscretion, your veterinarian may advise you to withhold food for a short time, until vomiting appears controlled. After this time, you may be advised to feed your dog a bland, easily digested diet.
If your dog`s vomit is slimy or mucus-like it might be because they`ve been drooling excessively and the drool has then pooled in their stomach. Typically this will look clear in appearance. This can be indicative of a major irritation, so if the slimy vomit persists, you should consult a veterinarian.
It is important to give your dog`s digestive system some time to recoup and rest from the vomiting by not feeding your dog for 12-24 hours. You can give your dog small amounts of water to keep them hydrated. Food and large amounts of water will only aggravate your dog`s upset stomach.
After a dog vomits, it`s generally best to withhold food for several hours and observe, but don`t withhold water. 2 If your dog vomits one time and then acts completely normal, you can probably resume your normal feeding routine within six to 12 hours or when the next meal is due.
Wincing, Whining or Crying

All three of these actions indicate an injury or some kind of pain your dog is experiencing. If you start to pet your dog and they shy away from your hand or whine, you know there is something wrong.

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. 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.

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. 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. 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 do I desensitize my dog to squirrels and stray cats in the neighborhood?
ANSWER : A. It depends on the goal that you have in mind. I am going to assume that you would prefer that your dog not chase squirrels or stray cats in the yard/street. In this case, your options include: (1) training your dog on a “Leave it ” cue using positive reinforcement methods, (2) training your dog not to pull on its leash when it sees a squirrel/stray cat, and (3) training your dog to perform a more desirable behavior when it sees a squirrel/cat.
Training your dog on a cued “leave it” command is useful because it will give you the ability to tell your dog to stay away from any number of undesirable objects on your command. Training your dog to perform a more desireable behavior when it sees a squirrel or cat will substitute a behavior you find acceptable (sitting, laying down, coming to the door, etc.) with a behavior you dislike. Your dog can still react, just in a positive way. If your dog pulls on the leash every time you see a squirrel/cat, training not to pull will make your walk safer and more pleasant.
The ideal training method to use with dogs, or any animal for that matter, is positive reinforcement training, particularly a method called “clicker- training.” The basic concept of positive reinforcement training is to pair a reward (reinforcement) with a behavior you want to increase in frequency. In other words, when your dog performs the behavior you desire, it receives an award, which reinforces the desired behavior so you get more of that behavior. There are many excellent books in stores or on-line that describe positive reinforcement training in detail and many give step-by-step instructions for training common commands like “leave it”. Look for books that specifically mention positive reinforcement training or clicker-training. You can also take dog training classes to learn the techniques, find a mentor who already uses clicker-training, or request a consult from one of the pet experts on this site to guide you.
