How to Identify Common Pet Problems ?

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

Generally, the symptoms of food poisoning in dogs include some combination of vomiting, diarrhea, reduced appetite, lethargy and dehydration. Some animals may show some neurological signs such as a lack of coordination, tremors and, in severe cases, even seizures and collapse.
You`ll want to watch your dog`s stool for several days (at least 72 hours) after they eat the bone for signs of bone fragments. In addition, you should still follow up with your vet in case there`s any remaining bone left in your dog`s intestines or esophagus. The bones can splinter and puncture these internal organs.
If your pooch does chow down on a chicken bone and appears to be in any kind of distress, act quickly and contact a vet for emergency treatment right away. If your dog looks to be acting normally, the bone will likely pass through the GI tract. Monitor the situation closely.
Check your dog`s stool daily to see if you can see the bone fragments passing through. If you do not see them within 72 hours after ingestion (or whatever time frame is recommended by your veterinarian), it`s a good idea to visit the vet to make sure the bones aren`t stuck in your dog`s intestine, esophagus or throat.
Some toxins cause reactions right away, while others cause symptoms several hours or days later. For instance, the first symptoms of antifreeze poisoning can appear in as little as 30 minutes, whereas the symptoms of chocolate poisoning take between 6 and 12 hours to show up.
In fact, according to PetMD, the canine digestive system takes anywhere from 8 to 10 hours to digest a meal fully, but it can take as long as 12 or as quick as four depending on your dog`s breed and the type of food consumed.
Generally, it takes between 6-9 hours for food to completely pass through your dog`s digestive tract. However, as dogs age, diet and even their breed can all be influential factors in reducing or increasing the time it takes your dog`s digestive tract to complete a full cycle.
Considering how many dog foods contain chicken as an ingredient, it`s a safe bet that you can feed your dog chicken. In fact, it`s a good source of protein, and cooked chicken can even be substituted for or added to his regular meal.
Once they reach the dog`s stomach, acids and enzymes normally dissolve chicken bones.
These lightweight bones break into shards that can tear the throat or puncture through the intestines. The bones and their pieces can also quickly lead to choking and airway obstruction in dogs. Chicken bones are dangerous to dogs whether they have been cooked or not.
How long does it take a dog to digest a bone? The chicken bone will probably pass within 24 hours, but factors such as your dog`s size, breed, age and even diet will influence this. Some dogs may take over two days to pass the bones.
The vast majority of dogs who eat a small chicken bone, especially if they chew it up, can pass it without an issue,” says Dr. Myers. If your dog has been vomiting for more than 24 hours, however—especially if you haven`t been feeding them in that time—you and your pup should head to the vet.
Poison Control

Consider using hydrogen peroxide (one teaspoon per five pounds of body weight), to induce vomiting. Dr. Putter advises using hydrogen peroxide (which is a gastric irritant) under consultation with animal poison control.

Acidophilus – Give your dog or cat acidophilus capsules mixed with water, or a small amount of live cultured yogurt or kefir (see dose instructions below). Give yogurt once every hour (up to three times) after the vomiting has ceased.
Dogs can safely eat chicken and often thoroughly enjoy it. However, you shouldn`t feed your dog raw chicken, and you need to keep the bones away from your furry friend. It`s also best to serve freshly prepared chicken without the seasonings to your pup.
Plain, unseasoned, boiled, shredded chicken is easy to digest and is packed with essential vitamins, minerals, fats, and amino acids, making it a great snack for dogs feeling under the weather.
Yes, dogs can eat cold, cooked chicken as long as it`s part of a nutritionally completed and balanced recipe.
The only reason that chicken will typically give your dog diarrhoea is if you`ve not prepared it properly; that`s to say, if it`s undercooked, if you`ve not removed the skin (as this contains fats that can cause nausea) or if it`s been seasoned, flavoured or had other preservatives added to it.
Gastric hypomotility typically occurs in older dogs, and results in vomiting undigested or partially digested food hours after eating. This cluster of diseases can be primary or secondary, meaning it is caused by a stomach issue vs something outside of the gastrointestinal tract, respectively.
A ⅛ cup of fluid per hour is enough to rehydrate small pets while a ¼ cup of fluid per hour is good for larger canines. If your pet is showing signs of severe dehydration, call your vet right away. Monitor your dog`s condition – Check to see if your pet will feel better within the next few hours after getting hydrated.
How Long After Eating Does a Dog Poop? Most dogs will poop about 30 minutes after eating, or immediately after waking up. These are both great times to plan walks or exercise for your dog. Of course, all dogs have different schedules, so you`ll learn what works best for your dog.
If your dog has digestive system issues, he may benefit more from boiled chicken. Boiled chicken is easier to digest than baked chicken.
Is Boiled Chicken Good For Dogs? Boiled chicken is an excellent source of low-fat protein, vitamins, minerals, and other necessary nutrients for dogs. It`s also often recommended along with rice by veterinarians for dogs with an upset stomach or diarrhea.
When a person eats food with lots of sugar, like candy, the acid breaks it down pretty quickly. Foods that are higher in protein take much longer. That barbequed pork you ate for dinner a few nights back? Your stomach acid may have taken up to four hours to break it down.

Q. My dog has been throwing up a clear liquid (a little slimey) but otherwise acts fine. Could something be wrong?
ANSWER : A. How long has he been doing this? Ongoing vomiting (>2 weeks) warrants a vet visit, but if it’s a one-off, or happens very infrequently then it could be due to something he ate disagreeing with him. Is he is bright, alert and happy in himself I would monitor him, start keeping a vomit journal (seriously) of when he vomits, how much, what the vomit was like, what he was doing before and any other notes. This will be really useful for your vet if it requires further investigatoon. You can also try bland food – boiled chicken and white rice – in small amounts on his vomit days to give his tummy a rest. Withhold for 8h after a vomit and reintroduce the bland diet in small, frequent meals.

Q. Should I be concerned if my cat ate a drop of habanero hot sauce?
ANSWER : A. If it was just a drop your cat will likely be fine. It is surprising that she tried it at all, as most pets do not like the taste of spicy flavored foods and it is actually used as a deterrent in training!

If your cat ate a larger amount, she may experience some digestive upset such as vomiting or diarrhea. A bland diet of plain boiled chicken can help soothe an upset stomach before returning to her regular food.

However, if the vomiting continues for more than a day, or she shows signs of illness such as confusion, disorientation or shaking, it may be that she either ate something else potentially toxic, or ate too much of the sauce and is experiencing adverse effects. These symptoms should be brought to the attention of your local vet or emergency clinic for care.

Q. Does an indoor cat need to be vaccinated every year?
ANSWER : A. In practice, I recommend a feline combo vaccine every year, but will generally start administering every 3 years once they have had their kitten vaccines and 2 additional yearly vaccines. Rabies, is required yearly by law, and if kept up to date can be good for up to three years also. Based on the age of your cat I would give a yearly feline combo and rabies, and then boost the combo again next year.

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. Great Dane, Lab mix is vomiting, lethargic, bloodshot droopy eyes. No appetite. What’s wrong?
ANSWER : A. Vomiting is a common symptom of many illnesses which can range anywhere from minor digestive upset, to mores serious problems such as disease, illness or even bloat.

If your Dane Mix has only vomited once or twice, it may just indicate a minor stomach upset. Picking up food for a few hours then feeding a bland meal of boiled chicken and plain rice can help soothe the stomach and entice eating. However, if the vomiting continues or symptoms persist for more than a day, it may indicate something more serious going on and should be looked at by your vet.

Large and giant breed dogs are more prone to a condition called Bloat, which is considered a medical emergency. Signs of bloat in a dog include a large distended abdomen, pain in the abdomen, signs of distress such as heavy panting, pale gums or tongue, vomiting and diarrhea, or attempting to vomit or defecate without success. If you suspect your dog may be experiencing bloat, contacting your vet or emergency clinic immediately is best.

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).
