How to Identify Common Pet Problems ?

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

Dogs that eat too quickly do have the potential to choke on their food. Luckily, there`s a simple and inexpensive solution to correct this behavior. Specialized dog food bowls known as `slow feed` or `puzzle feed` dog bowls help dogs that eat too fast slow down and take smaller bites.
This condition usually happens when there is an underlying problem with the normal reflexes of swallowing and pushing material down the esophagus. In aspiration pneumonia, food makes its way into the airways and is inhaled into the lungs.
Sometimes, the cough or gag is a result of your dog eating too fast and the food going down the “wrong pipe” (the trachea, which leads to the lungs, instead of the esophagus, which leads to the stomach). Just keep a close eye on your pup after an incident like this.
Gulpies appear to happen more frequently after food, it may be an allergy to certain foods, or feeding a `low fat` diet. It could be helpful to split the food into smaller portions and feed 2, 3 or 4 times a day. Feed the last meal later in the evening so that the dog does not have an empty stomach for too long.
Unlike other illnesses, esophageal obstruction in dogs is due to swallowing foreign objects. If the item cannot get to the stomach and come out through the bowels, it is usually stuck somewhere in the esophagus, leading to regurgitation or vomiting.
Unfortunately, dogs frequently choke. This is because dogs are inquisitive and will often chew on anything they can get hold of: from plastic bags to sticks, socks and toys. If it goes down the wrong way, it may leave them unable to breathe.
Pharyngeal dysphagia is when the dog can grab food, but must repeatedly attempt to swallow while flexing and extending the head and neck, chewing excessively and gagging. While food is retained in the cheek folds of the mouth, it is saliva-coated.
Dogs eating too fast can cause health issues

And when dogs gulp their meal too quickly, they swallow air along with their food. Food and air expand in the stomach, causing pain and discomfort. This can cause your dog to vomit or regurgitate and lead to a serious condition called gastric dilatation-volvulus, or bloat.

Aspiration pneumonia is a lung infection that can develop if your pet inhales foreign material, such as food, liquid, or stomach contents. Foreign material that contacts the delicate tissue lining the lung`s airways causes inflammation, and the lungs become susceptible to infection.
Reverse sneezing itself rarely requires treatment. If the sneezing stops, the spasm is over. Oftentimes, you can massage the dog`s throat to stop the spasm; sometimes it`s effective to cover the nostrils, which makes the dog swallow, which clears out whatever the irritation is and stops the sneezing.
Dysphagia, a common problem in dogs, is the medical term used to describe difficulty in swallowing. Dysphagia has many different causes, some of which are treatable and some are not.
A dry, hacking cough can sound like a dog is trying to dislodge something from the throat or mouth. A raspy-sounding, hacking cough can be a symptom of kennel cough, a contagious upper respiratory illness that dogs often get from places where many dogs congregate.
I do my best to monitor his food and eating to prevent him from choking, but the fact of the matter is that dogs can choke on just about any food. Everything from regular kibble to uneatable objects can pose a potential choking risk, especially to dogs who feel that chewing food is overrated.
Choking can be a “silent but deadly” situation—the less you hear, the more urgent the problem may be. A choking pet will look distressed: they`ll probably have their mouth open and be trying to cough—either with sound or just silent heaving—and they might be pawing at their face.
Sometimes when dogs become excited or anxious they can cough. This is usually seen in dogs with tracheal collapse (where part of their windpipe has begun to collapse) because their heightened state of excitement or anxiety means that they are breathing harder.
Acute oesophageal symptoms require a careful history: dysphagia may be confused with globus and with early satiety. Acute food bolus obstruction is readily recognised but the underlying causes may be subtle (Schatzki ring, eosinophilic oesophagitis or motility disorders) and easily missed at endoscopy.
A feeding disorder refers to problems in the development of feeding skills, such as sucking from breast or bottle, eating from a spoon, chewing, or drinking from a cup, while a swallowing disorder, or dysphagia, refers to problems in one or more phases of the swallowing process (Table 2) [9].
Maybe serve a single food at a time. Eating smaller meals more frequently may help get in adequate calories, if big meals tire your loved one. Drink fluids (including soups and shakes) throughout the day. Increase calories by adding cream, butter, sour cream or milk to recipes, and jellies or honey to sweeten foods.
Treats: esophageal dysphagia

Your gastroenterologist may recommend surgery if therapy and medication don`t improve or resolve your dysphagia. If your dysphagia is caused by an obstruction, surgery can be used to remove it. If your dysphagia is being caused by a narrowed esophagus, a stent can be placed to open it up.

They`re Eating Too Fast

If your dog is throwing up after eating too fast, they will likely have other symptoms as well, such as bloating and nausea. To prevent them from eating too fast, give them smaller amounts of food multiple times throughout the day or use a food puzzle to slow them down at mealtime.

Causes of Pneumonia in Dogs and Cats

Aspiration pneumonia occurs when something such as food or liquids “go down the wrong pipe.” That is, instead of going down the esophagus into the stomach, they end up going down into the windpipe (trachea) into the lungs.

Pulmonary edema is characterized by a buildup of fluid in the dog`s lungs that may be due to a variety of underlying health conditions, exposure to toxins, or due to trauma. Pulmonary edema occurs if the tiny clusters of air sacks within the lungs called alveoli fill with fluid instead of air.

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. 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 cocker spaniel is 9 years old. He has involuntary bowel movements (little drops) very frequently, especially when he is asleep.
ANSWER : A. Is your dog on a senior dog food? I would get your dog on a high quality high protien dog food. Ask a pet store assosicate or your regular vet for a food recommendation. When you buy a better food the dog will have to eat less to get the same amount of energy from the food. The dog has to eat more of the cheaper foods to get the energy it needs from it. Meaning more poop and buying more food. So the cost really evens out. So the lessen your dogs bowel movements get on a better senior dog food. Next talk to your vet they may have a recommendation. If you switch dogs do it slowly by mixing the foods. Start with 10% new 90% old mixed for at least a week until you have switched to 100% new 0% old. Senior foods have more fiber to help with bowel movements. Take the dog outside to go potty more frequently, right before bed time.

Q. My 20 month Cavalier doesn’t eat unless I let him eat from my finger, then he eats. Sometimes he will only eat once a day and leave his food.
ANSWER : A. It is possible that your dog is just not satisfied with his current food, or may be a picky eater. There are several things you can try to encourage your dog to eat.

The first step is to remove any additional treats or people food that may be more enticing to your dog than his own meal. If you feel you must give him some form of treat, be sure to place them directly in his food bowl and mixed with his regular diet. This allows him to get some snacks while also “forcing” him to try out his current meal to get the reward.

Enticing your dog to try his food by adding a pet-safe gravy or even a few treats of plain boiled chicken mixed in can help. Be sure to mix the foods thoroughly so he must explore his own food before getting the treat.

Some small breed dogs may also have a hard time with certain bowls and their collars. If there is a metal name tag on the collar and a metal bowl, the clinking sound can sometimes scare off dogs and make them not want to eat from their bowl. Using a bowl of a different material, or removing the collar prior to a meal may help with this issue.

Your dog may also just not be into his current food and may like another variety better. You can try a new variety by gradually switching over a period of 7-9 days, slowly adding in more new food and removing old until it is switched. This change may encourage him to try out meals again, and the slow changeover will allow his body to adjust to the new diet without digestive upset.

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. 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. What is the best limited ingredient dog food for a dog with allergies? Can I buy it online or do I need to get it from a vet? Thanks
ANSWER : A. I’m going to recommend a dog food that is extremely expensive, but absolutely worth the price. It is a food that is fantastic for dogs with many allergies because it is essentially just air-dried raw meat, muscles, vitamins, and kelp. It is called Ziwipeak http://ziwipeak.com/ and it is the best dog food on the market! I feed it to my dog so I do not have to worry about getting raw-food portions right. If you’re worried about the price, there are so many other types of food out there you’ve probably never heard of. You do not have to get food through the vet in order to find the right food for your dog. Many grain-free foods are typically good for dogs with allergies, brands like Merrick, Taste of the Wild, Orijen, etc are great kibbles. It may be pricey, but it’s all about trial and error here unless your vet can tell you exactly what the allergy is and how to manage it.

Q. My dog won’t stop eating cat litter, old diapers and she even tried eating glass
ANSWER : A. Don’t let your dog have access to cat liter and old diapers. Have a trash with a lid for the diapers and put a hood on the cat box or put it in a room the dog can’t get to. If your dog is trying to eat other things maybe he’s looking for more nutrients in his diet that his food isn’t giving him. Look for a higher quality high protien food at the pet store. Have someone help you at the pet store pick out a food or ask your regular vet their food recommendation. One with the first ingredent as a meat like deboned chicken. If your dogs foods main ingredient (first one listed) is a corn or chicken by product that is bad. You will need to slowly transition the dogs food over by mixing the foods and slowly adding more new and less old to the food for at least a week.
