A. Given his age and the duration of symptoms, a visit to your vet for an exam and diagnostics (blood work, abdominal xrays) would be the first recommendation. At this point in time, he may require supportive care (fluids, medications) if he is dehydrated and not eating well. If that is not possible, try withholding food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet (1:1 ratio of plain boiled boneless chicken and plain white rice). Feed in small, frequent amounts waiting at least one hour between feedings. Serve it warmed or mix in baby food to stimulate the appetite. If the vomiting stops, continue feeding until the stool is normal. Transition slowly to the regular diet. If the vomiting or diarrhea don’t stop or he doesn’t begin eating again, you will need to see your veterinarian.

How to Identify Common Pet Problems ?

Gastroenteritis is inflammation of the gastrointestinal tract (stomach and the intestines). It can be caused by infection with bacteria, viruses, parasites, medications, or even new foods. The condition often causes abdominal pain, diarrhea, vomiting, and other clinical signs.
Pets that have chronic soft stool or chronic full-blown diarrhea should definitely be examined by a veterinarian, even if they are otherwise behaving normally. In these cases, there is likely an underlying problem that`s causing the diarrhea. This is especially true with older pets.
Contact your vet right away if your pooch is experiencing repeated episodes of diarrhea. Dogs showing other symptoms as well as diarrhea should also be seen by a vet as soon as possible. If your dog has any of the following symptoms, contact your vet right away to make an appointment: Lack of Appetite.
Dietary Changes, Allergies, and Food Intolerance

A sudden alteration in your dog`s diet can lead to problems in their gastrointestinal tract, manifesting as clear liquid in vomit and diarrhea. For a smoother transition to a new diet, introduce it gradually over a period of 7 to 14 days.

However, if your dog is not eating and is either vomiting, having diarrhea, or both, contact your veterinarian within 8-12 hours.
The cause of an old dog throwing up has ranged from something simple, like the dog eating too many dog treats, to more complex issues, like liver or kidney disease. Senior dogs, like puppies, are not as resilient and may become significantly and more rapidly affected by vomiting compared with adult dogs.
This behavior has a name– Fecal Incontinence – and it is not an unusual occurrence with senior dogs. A number of physical/cognitive problems related to aging can cause fecal incontinence, including weakened or damaged anal sphincter muscles, spinal nerve damage, or cognitive decline.
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.
Ginger is one of the best home remedies for your dog`s vomiting and upset stomach. You can make ginger tea by boiling fresh ginger root in water, cooling it, and giving it to your dog in small amounts throughout the day.
Possible causes of a dog vomiting or regurgitating white foam include indigestion, acid reflux, dietary indiscretions, infections, heat stroke, kidney disease, parvo, pancreatitis, and bloat (many dogs with kennel cough may also bring up white foam, which can be mistaken for vomiting).
How Long Can a Dog Go Without Food? Dogs can usually go three to five days without food, however, this is not ideal. If your dog has gone two days without food, it is highly recommended you call a veterinarian if you haven`t already. More important than your dog eating is their water intake.
For feeding a sick dog that won`t eat, most vets recommend bland chicken with white rice or white meat from a rotisserie chicken. Other options are sweet potatoes, unseasoned pumpkin (not pumpkin pie filling!), bone broth, and meat-based baby food. Lastly, you can try hand-feeding your sick dog.
Dogs may go off their food because of changes in their environment, stress, an adverse reaction to drugs, and nausea. Dental problems, pain and internal obstructions can also cause dogs to lose their appetite.
Senior dogs are much more susceptible to illness and disease than younger dogs, including conditions such as cancer, heart disease, diabetes, arthritis, vision and hearing loss and cognitive dysfunction.
While vomiting may be a sign of stomach upsets, it`s often an indication of a more serious underlying problem in older dogs. Therefore, you must seek veterinary help if your senior dog is throwing up consistently.
Beyond rice, other simple foods that can help relieve your dog`s diarrhea include pumpkin, cottage cheese, peeled boiled potatoes and plain chicken breast. Remember, this bland diet is not balanced, so do not feed it to your dog for more than a few days.
Less interest in food is a normal sign of aging for dogs, but not eating for more than a day or avoiding drinking their water are both good reasons to call the vet. Whether your senior dog is slowing down or still a puppy at heart, they need the right nutrition.
Giardiasis is a common parasitic infection that can cause diarrhea in dogs. It is caused by an intestinal parasite called Giardia, which can be found in feces-contaminated soil, food and water.
Adult dogs should poop one to three times a day, though puppies poop more often (up to five times a day or more), and senior dogs may poop once a day.
Small dogs are considered senior citizens of the canine community when they reach 11-12 years of age. Their medium-sized friends become seniors at 10 years of age. Their larger-sized colleagues are seniors at 8 years of age. And, finally, their giant-breed counterparts are seniors at 7 years old.
The most common symptoms of a fever in dogs are: Red or glassy-looking eyes. Warm ears and/or nose. Shivering.
Symptoms of Parvo

Your dog will not drink water nor eat, and very soon the pup will be stretched out and down on the ground, unable to get back up. They will become limp, weak, and unable to hold themselves up. Parvovirus, when left untreated, is often fatal. It requires veterinary oversight.

Physaloptera are stomach worms that attach to the gastric mucosa of your dog. The worms can cause chronic vomiting, and lead to further complications. The presence of even one worm can be harmful; they are quite large. Some canines remain asymptomatic while others become very ill with a physaloptera infestation.
Intestinal parasites can cause diarrhea, weight loss, rough hair coat, and/or a pot-bellied appearance. Vomiting can also be seen, sometimes with worms in the vomit.

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. Hollywood is 15 yrs; he’s been vomiting, not eating much & has had runny diarrehea for 3 days now. Help
ANSWER : A. Given his age and the duration of symptoms, a visit to your vet for an exam and diagnostics (blood work, abdominal xrays) would be the first recommendation. At this point in time, he may require supportive care (fluids, medications) if he is dehydrated and not eating well. If that is not possible, try withholding food for 12-24 hours.

Q. Cat was vomiting for a few days. Took to vet, received anti-nausea medicine 2 days ago. Drinks and no longer vomits, but won’t eat. I’m worried
ANSWER : A. If your cat has been feeling nauseated, it is possible that the nausea, or just general illness is making him want to eat less. However, you can try enticing him to eat with a few tricks geared to cats.

Warming up wet foods or even bland people foods such as plain chicken or boiled hamburger can make food more interesting to cats. Cats tend to go for aromatic rather than flavorful foods, so making the food as “smelly” as possible may encourage your cat to take a bite. Bland foods are also good for helping to soothe upset stomachs, which may still be happening if your cat had recently had a vomiting episode.

However, if enticing your cat to eat does not work, or he continues to refuse to eat any food, it is best to contact your local veterinarian for more care and testing. Cats can become very ill if they refuse to eat for more than a few days, and finding the underlying cause can help your cat feel better.

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. 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. Why does my dog eat grass? He throws up afterwards!
ANSWER : A. There is much debate over why dogs eat grass and then vomit afterwards. One theory is that the dog may have an upset stomach, and so eats the grass blades which then irritate the digestive system and causing vomiting to happen. Another theory is that the dogs are eating grass to mimic a “lost nutrient” of their ancestors found usually by hunting and then eating the contents of the stomachs of herbivores. A third theory is that dogs just do it because to them, it’s fun and they can.

If your dog has been vomiting a lot recently, either related to or unrelated to eating grass, then it is always a good idea to schedule a wellness exam with your vet to make sure there are not any issues causing illness. Grass, especially in areas where livestock may graze can also be a host for parasite eggs, which can in turn infect your dog with an internal parasite (and thus cause vomiting and diarrhea).

If your dog is not eating at all, this is more concerning and points further to some digestive upset causing his or her symptoms. Making an appointment with your vet as well as bringing in a sample of his or her stool is best for helping your pet feel better.

Q. My dog hasnt eaten snce I left 4 days ago. I won’t be home for 6 more days. How can the caretaker get her to eat?
ANSWER : A. If your dog is feeling a bit sad while you are away and is refusing to eat, your pet sitter may try some things such as adding in boiled chicken or turkey to meals to encourage eating. A pet-safe gravy may also entice your dog to eat as well while you are gone. Your pet sitter may also want to offer smaller meals more often throughout the day to give your dog more chances to try and eat when she is feeling more comfortable and a little less sad. A game of fetch or playing together may also get your dog’s appetite going and help her to feel more comfortable eating around your pet sitter.

If your dog is showing any other signs of illness in addition to the refusal to eat (beyond normal missing an owner), then it is always a good idea to keep an eye out and contact a veterinarian as needed.

Q. My 8mo. puppy eats feces. Wedont scorn him for pottymishaps. He hides feces in his bed.I feed him blue buffalo 2 per day. How do I stop this?
ANSWER : A. A lot of dogs do this, and sometimes it is just because feces tastes good.. sometimes it is due to something lacking in their diet.. but a lot of the time, it’s just fun and tasty. The only way to handle this situation is management. You should be cleaning up your two dogs poops immediately when they happen. Scoop them up, throw them into the woods, or into a can. You cannot give your pup access to the poops.

You could also try adding things to your pups diet. Things like canned pumpkin for dogs (not the pie filling you find in the grocery store, that has way too much sugar in it). Or you could feed your dog raw chews like marrow bones, or beef tendons. You’ll have to add things to his diet in order to find out what is missing from it. If you allow him to continue eating poop, even if there is something lacking in his diet, he will continue eating poop when you’ve solved his diet issue because it will become a LEARNED behavior. This means he will continue eating poop because he learned he CAN eat poop. You could also try feeding him three meals per day. Feed him the same amount of food, but break it up into three feedings per day. This could help him feel a bit more full throughout the day.

Clean up your yard, and clean up after your pups immediately when they eliminate outdoors. Do not scold him, there is no need.. it isn’t his fault.
