How to Identify Common Pet Problems ?

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

In addition to an inability to control their bowels, a dying dog may vomit after eating or drinking. If your dog is not able to keep water down, they may become dehydrated. During this time, you may try to keep your dog hydrated by giving them water from a water dropper or turkey baster.
However, vomiting can also be a sign of more serious illnesses such as allergies, bacterial or viral infections, inflammatory conditions such as pancreatitis, intestinal obstruction from foreign bodies (something eaten that gets stuck in the intestine), organ dysfunction such as liver or kidney failure, or cancer.
The reality, however, is that natural death is not usually peaceful, and dogs with terminal illnesses could suffer for days from pain, nausea, and anxiety as their bodies begin to shut down. This is why the standard is for veterinarians to offer painless, humane euthanasia to end a pet`s suffering.
Labored Breathing

This change may take place just hours or days prior to death and is a sign that the dog`s body is beginning to slowly shut down.

As the moment of death comes nearer, the person`s breathing may slow down and become irregular. It might stop and then start again or there might be long pauses or stops between breaths. This is sometimes known as Cheyne-Stokes breathing.
Symptoms of stomach cancer in dogs usually develop gradually over weeks or months, with vomiting being the most common. This is often the first sign and it may appear blood-tinged or resemble coffee grounds as the condition progresses. This is due to ulcerating tumors, or tumors that break open and bleed.
This can be due to gastrointestinal pain caused by the ingestion of food from the garbage, table scraps, or chew toys. The pain may also be due to something more serious, such as roundworms, viruses, or diseases. Sometimes it`s nothing more than motion sickness or stress.
Vestibular disease is the main reason why an older dog may experience a sudden loss of balance and an inability to stand or walk normally. How can you tell if a dog has a vestibular disease? A few of the signs include dizziness, stumbling or wobbly steps, and falling over.
Why Pet Loss Hurts. “One reason why losing a pet is such a deep loss is because animals` love is so unconditional and accepting,” she said. But it`s also because so many aspects of people`s lives are impacted. “Every single facet of life is part of the loss,” she explained.
The most prominent sign that you will notice is a complete relaxation of the body, your dog will no longer appear tense, rather they will “let go.” You will notice a slimming of the body as the air is expelled from their lungs for the last time and you may notice the lack of life in their eyes if they are still open.
One stage of this process is known as rigor mortis. This is when the energy supply to the pet`s muscles deplete. When this occurs, everything becomes stiff. The average time for “rigor” to set in is 3-4 hours and it is typically complete within 12 hours post death.
Changes in breathing

You may develop Cheyne-Stokes breathing, when periods of shallow breathing alternate with periods of deeper, rapid breathing. The deep, rapid breathing may be followed by a pause before breathing begins again. Your breathing may also become more noisy as a result of the build-up of mucus.

Gasping is a brainstem reflex; it is the last respiratory pattern prior to terminal apnoea. Gasping is also referred to as agonal respiration and the name is appropriate because the gasping respirations appear uncomfortable, causing concern that the patient is dyspnoeic and in agony.
Certain breeds, such as German Shepherds, are also more prone to developing chronic pancreatitis. Miniature Schnauzers, Yorkshire Terriers, Silky Terriers and Miniature Poodles may be at increased risk of developing pancreatitis.
Pancreatitis in dogs is an inflammatory reaction within the pancreas that can result in abdominal pain, inappetence, and vomiting. The inflammation results from the inappropriate, early activation of an enzyme within the pancreas, which causes the pancreas to digest itself.
Certain cancers.

Brain tumors, liver tumors, and GI tumors are more likely to cause nausea and vomiting. Dehydration, infection, pain, and other problems. Nausea and vomiting may be caused by other symptoms and side effects.

Vestibular signs include:

Circling to the side of the head tilt. Involuntary flicking of the eyes (nystagmus) Loss of appetite and vomiting.

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. In addition to vomiting frequently, your puppy may also appear to be drooling or foaming at the mouth as part of their parvo symptoms. Your puppy`s nose may also begin running.
Gastric dilatation-volvulus (GDV) is a serious condition and is fatal if left untreated. Commonly referred to as “bloat,” GDV occurs when a dog`s stomach fills with gas, food, or fluid and subsequently twists. GDV develops without warning and can progress quickly. It is always an emergency.
Dogs feel pain for many of the same reasons as humans: infections, dental problems, arthritis, bone disease and cancer. They also feel discomfort following surgical procedures. Unfortunately, unlike humans, they are unable to speak to us about when and where they hurt.
When a dog yelps for no apparent reason, it may be due to neck or back pain, which is common in canines. These issues could be a result of degenerative diseases, injuries, or infections. Dogs with neck or back pain may yelp when jumping, walking, or lying down.
14 years old can generally be considered old for a dog. A small dog is considered old when they`re 11, a medium dog is considered old when they`re 10, and a large dog is considered old when they`re 8.
Some people start to feel better in weeks or months. For others, the grieving process is measured in years. Whatever your grief experience, it`s important to be patient with yourself and allow the process to naturally unfold. Feeling sad, shocked, or lonely is a normal reaction to the loss of a beloved pet.
It`s normal, and though painful, it`s part of the grieving process that`s necessary for you to heal. “Most people who have bonded with a pet know the comfort and joy animals provide. When we lose a pet, part of us feels like it`s dying. Pets may be the only time we experience unconditional love.”

Q. My 13 yo yorkie died; he vomited with pain,then seemed ok. He threw up again the next day,& had very rapid breathing, & later died. Why did this occur
ANSWER : A. I’m very sorry for your loss. The best chance at finding an answer would be to have your vet perform a necropsy on your dog. Even then though, you may not find a reason. I hope you find peace and closure knowing your pet is not suffering and is in a better place now.

Q. My French Bulldog (11 months) threw up after eating and is dry heaving, plus he’s not acting normal. His breathing is nasally and he’s lethargic. Help
ANSWER : A. Vomiting is a common symptom that can be a sign of numerous health issues ranging from minor digestive upset, to bloat or internal illness. If the vomiting has only occurred once and everything else is normal, a bland diet of plain boiled chicken and white rice can help.

Since your Frenchie is having other issues such as trouble breathing and lethargy, it may be a good idea to contact your vet for advice. Minor digestive upset can cause lethargy due to the energy expended in vomiting, however prolonged symptoms usually indicate something more serious is going on.

Bulldogs are one breed that are prone to bloat (though any breed of dog can be affected), a serious medical emergency. Signs of bloat can include a suddenly painful and bloated abdomen, signs of distress such as heavy panting, whining, or trouble breathing, pale gums and tongue, vomiting and diarrhea, or attempting to vomit or defecate without success. If you suspect your dog may be experiencing bloat please contact your vet or emergency clinic immediately.

Q. My puppy is throwing up her food this morning and yellow foamy stuff. Please help!
ANSWER : A. If the vomiting has only occurred once, it may be due to the fact that there was something causing a minor upset stomach in your pup. Yellow foam is often acid, and tummies that are upset or that have been empty for too long can cause this to appear in vomit. It may just be that your puppy needs an extra meal in the day to help keep her stomach happy. Eating a meal too quickly can also cause a pup to vomit up undigested food and foam, and feeding smaller meals more often, or slowing down your dog’s eating can help.

If the vomiting has only happened once, pick up your puppy’s food for an hour or two and then offer a bland meal of plain boiled chicken and plain rice. These bland ingredients can help settle upset stomachs while being enticing “people food”. If the vomiting does not occur again, you can return to a normal feeding schedule.

However, if the vomiting continues, worsens, or new symptoms appear along with it, then it is a good idea to schedule an appointment with your vet to rule out any more serious causes.

Q. He is not eating or drinking seems like he has no energy and vomiting and seems like he weak
ANSWER : A. Causes of not eating and vomiting can be many. Gastrointestinal infection, caused by bacteria (salmonella, for example) or viruses or parasites (although parasite infections tend to be more mild, but giardia can make them feel pretty bad) can be a cause. Eating something he shouldn’t have, like the trash or rotten food can cause it. Intestinal obstruction can cause vomiting as well. Other causes (non-GI) of vomiting include kidney failure (can be due to many things, such as toxins, kidney stones, cancer) or liver diseases or liver failure.

The vomiting is concerning, however the weakness and lack of energy implies that he’s either seriously dehydrated or there’s a lot more going on than just s simple case of vomiting. He needs to see a vet and have testing, likely to include x-rays and/or blood work, to see what’s going on, so that it can be treated.

Q. What are the typical symptoms for parvo, and what is the treatment?
ANSWER : A. Canine Parvovirus is an extremely contagious disease where infected animals shed billions of virus particles in their feaces during the illness and up to 2 weeks afterwards.

Infection occurs through the oro-feacal route, the virus is extremely resistant and can remain infectious for many months in the environment.

Clinical signs occur 5 days after being in contact with the virus and include anorexia, lethargy, vomiting and profuse diarrhea, often containing blood. Symptoms can progress to sepsis and other complications, leading to death especially in young puppies or in predisposed breeds such as Rottweilers and Dobermans.

Parvovirus is suspected in all young dogs presenting with vomiting and diarrhea, lethargy and leukopaenia. Severe leukopaenia corresponds to a poorer prognosis. Diagnosis can be confirmed on a faecal laboratory test, with positive results being considered a reliable indicator of positivity for the infection.

Treatment is supportive and aimed at restoring electrolytes imbalances, correcting dehydration, prevent secondary infections and controlling hypogliacaemia. Aggressive intravenous fluid therapy is required until vomiting stop and eating starts again. Initially small amount of bland diet should be fed and a gradual transition to the usual diet should be made. Vomiting can take up to 5 days to resolve.

Q. What can I do at home for my 8-yr old cat who’s been vomiting “after” eating as if she’s renching? Seems to occur only after she eats (twice a day)
ANSWER : A. Sometimes cats are really greedy when you feed them and because the stomach receives the food too much rapidly is not able to retain the food and that’s why possibly is been happening. Try to split the meals instead of twice a day in 5-6 small meals. If you just allow her to small meals and the vomits disappear that’s diagnosed! If not go to your vet for a proper check up. If you confirm is just eating really quick you can buy especial bowls to slow down you cat when eating.

Q. Changed dog’s food. Now throwing up and with diarrhea, what should I do?
ANSWER : A. Vomiting and diarrhea can occur if food is switched too quickly. Dogs generally need a slow changeover of foods over a period of a week or so to allow their guts and the gut bacteria to adjust. If there has only been one vomiting and diarrhea episode, removing the food for a few hours then feeding a bland diet of boiled chicken and plain rice can help soothe the stomach. You should then return to his old food and begin a gradual changeover of foods starting with 3 days of 75 old/25 new, 3 days of 50/50 and then 3 days of 25old/75 new. However if the vomiting and diarrhea symptoms do not improve, it may indicate something else causing his digestive distress and an appointment should be made with your local vet.

Q. My puppy acts as if he may have the flu. Lack of appitite, mucus like vomit. On day two. Should I be concerned? He will drink a little water.
ANSWER : A. We always suggest that puppies are checked sooner rather than later, as they can go downhill rapidly, just like babies do. Vomiting can lead to dehydration and can cause serious consequences when pets are young. I would take him to your regular vets, bringing along your vaccination and worming/parasites records, and report on when the illness started, how frequently he vomits and when, what does he vomit, how often he goes to the toilet, what do you normally feed him etc.
