A. I would also add to the information below that while dogs occasionally will go “off their feed” during a heat cycle, vomiting and diarrhea isn’t normally associated with heat. If her symptoms don’t resolve in 24 hours, or if she gets substantially worse (i.e. Vomiting that won’t stop, dry-heaving, blood in the stool) take her right in.

Answer: This is not uncommon due to the hormonal changes coming with the heat cycle and some dogs just get stressed when in heat. Please keep an eye on her and see your vet if you see any worrisome signs accompanying the diarrhea or the diarrhea gets severe.
If your pet is lethargic, refusing food or having bloody vomit or diarrhea, you should take him or her to your veterinarian immediately. If your dog is vomiting or having diarrhea, you should skip his or her next meal. After this, you can start feeding the bland diet.
THe most common reasons a puppy may refuse to eat include: stress and anxiety, environmental issues, digestive issues, illnesses, teething pain, and food preferences. If your puppy refuses to eat, it`s important to consult with a veterinarian who can diagnose and provide appropriate treatment.
There are times when a poor appetite can be expected. Female dogs in heat as well as the male dogs nearby frequently lose their appetite for a time. However, inappetence following a heat cycle can be a sign of pyometra, which requires an immediate vet visit.
Diet during Heat Cycle

Make sure your dog laps up a lot of liquids, be it water, chicken soup, or electrolytes as this will keep her energized. Fiber-rich food items like oats will keep her digestion in check. Offer her tasty food items. This can be anything that she likes in general.

Female dogs do experience cramps when they are in heat. In the same way that women get period cramps during their cycle, dogs may experience something similar during their heat cycle.
Withhold food for 12 hours if your dog has been sick and then gradually introduce bland food. Repeated sickness without any of these symptoms will also need veterinary attention.
However, if your dog is not eating and is either vomiting, having diarrhea, or both, contact your veterinarian within 8-12 hours.
Some tricks to getting your dog to consume water are to add a little water to his dry food making it moist. You can also give your pup ice to snack on. Dogs love the crunchy texture and there`s no additional calories! Try a new bowl or a new place to place the bowl to tempt him.
Dogs are naturally able to go longer without food but their tolerance for not drinking water is much less. At most a dog can go three days without water intake but can survive for five to seven days or more without food.
Heat usually lasts between 2-4 weeks. Early in the cycle, a female dog may not be receptive to male dogs, although some are receptive through the entire cycle. It can be shorter or longer and you`ll know the cycle is over when all her vulva returns to its normal size and there`s no more bleeding or discharge.
Appetite changes are common when female dogs are in heat. While the majority of dogs will experience a decrease in appetite, some may experience an increase (Farricelli, 2016). Whether your dog has a small appetite or if she is hungrier than usual, feeding her nutritious food is key.
Is your dog in heat? They may also be acting sick or not feeling well, or showing other potential problems, such as a swollen vulva, not eating, bleeding too much, or bad smells. Some signals can mean they need to see your vet. Sometimes, though, this is a normal sign of a dog in heat.
It`s important to keep an eye on your dog during hot weather to ensure they don`t overheat. Never leave them alone in a car, even with the windows open, and make sure they have plenty of shady spots in the garden and in the house to retreat to when things get too hot.
Do not leave your dog outside and unsupervised: A female dog in heat who`s also outside and alone is the perfect company for a passerby (or stray) male dog looking to mate. Walk your dog with a leash: To safely walk your dog while she`s in heat, you should always keep her on a leash despite her obedience skills.
Pyometra literally means pus within the uterus. This disease occurs in unspayed female dogs, most commonly a few weeks following estrus (being in heat). Vomiting is a common symptom associated with pyometra.
When signs of parvo start showing, the stool gets more watery, becoming brownish to black diarrhea with traces of blood. After signs of parvo start to show and diarrhea gets bloody and smelly, it`s a race against time because most dog fatalities happen within 2 to 3 days after the symptoms.
Parvo smell has a unique very bad-smelling poop that is not easy to forget. The smell has been described as metallic, with hints of blood stench since the virus affects the intestinal walls, and a seemingly sweet scent.
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.
Ingesting toxins or poisons. Medications such as antibiotics. Parasites – roundworms, hookworms, whipworms, Coccidia, or Giardia. Viral infections such as parvovirus, distemper, or coronavirus.
Soft stool can be normal in healthy puppies, but if a puppy that normally has firmer stool starts having soft stool monitor the change for 24 hours. If the soft stool continues for more than 24 hours or becomes diarrhea contact your advisor or area coordinator and start fasting the pup.
Diarrhea may or may not occur in dehydrated dogs, but it is common in dogs who are also vomiting. Just like vomiting, it can make your dog`s dehydration worse almost instantly, so he needs to go to the emergency vet right away if he is having diarrhea too.
If your puppy has diarrhea but is still playful and normal, there is no need to panic. It will likely resolve on its own. Here are the signs to call your veterinarian to schedule an appointment: Diarrhea that lasts more than a day.

Q. How do I get my dog to stop chewing on things? I kennel her when I leave for a few hours, but I can’t go to the mailbox without her eating something.
ANSWER : A. If she’s young, then this is just normal puppy behavior. Don’t worry about it. The thing about puppies is, they explore using their mouths. If your puppy grabs a coat hanger, or a slipper, you should roll up a newspaper, and smack yourself on the head with it for leaving those things out.. your puppy is going to explore things, that’s normal! It is 100% up to YOU to keep those things away from your puppy when your puppy is unsupervised… even for just a moment.

Remember to never scold your puppy for grabbing these things. They are just curious little cuties, and they don’t chew things up to bother us.. Dogs do not have intentional thought, so they aren’t ever doing anything ON PURPOSE to us.. The most important thing you can do when your puppy is chewing something you don’t want her to be chewing is TRADE her the inappropriate item with a toy of hers, so she understands “no honey, that isn’t what puppies chew on… THIS is what puppies chew on!” and then begin playing with her using her toy to show her that TOYS ARE FUN.. Way more fun than a boring ol’ coat hanger.

Another helpful thing you can do is have two bags of toys. In each bag is many different kinds of toys. Lots of chew toys, lots of soft squeaky toys, lots of rope-type toys, a bunch of balls.. All kinds of things! For one week you have bag#1’s toys out for your puppy to play with.. At the end of the one week, you collect those toys, and you bring out bag#2! The toys will be more interesting/feel like new to your puppy, which will in-turn, make her chew less inappropriate things. Her toys are too fun to care about that dumb Wii-mote that you left laying around.

Hope this helps!

Q. My puppy is in heat for the first time.she had diarrhea and vomiting.she won’t eat or drink anything. Don’t know what to do.
ANSWER : A. I would also add to the information below that while dogs occasionally will go “off their feed” during a heat cycle, vomiting and diarrhea isn’t normally associated with heat. If her symptoms don’t resolve in 24 hours, or if she gets substantially worse (i.e. Vomiting that won’t stop, dry-heaving, blood in the stool) take her right in.

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. My 2 months old rottweiler puppy isn’t eating properly. Shes only eating shredded or minced chicken but adding any thing means she won’t eat.
ANSWER : A. This is not a nutritionally adequate diet for your puppy. She needs to be eating a good quality puppy food. Put the proper amount in her bowl and put it down without any fuss. Leave it for fifteen minutes. After that, if she has not eaten, pick it up–again without fuss–and do not give her anything else to eat until her next scheduled mealtime, not even treats. When she is due to eat again, repeat the process. This may take quite a few days to resolve, as she will try to hold out for the chicken. Do not give in! Remember that you are not starving her. The food is there, but she is choosing not to eat. When she realizes that this is all she is going to get, she will begin to eat and your problem will be solved.

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. Wants to go out very frequently. Has fecal matter attached to anus but won’t let me remove it. She won’t sleep and wants to stay on my lap.
ANSWER : A. So I’m hearing a couple of problems going on. Frequent defecation with diarrhea (I’m assuming, since there’s fecal matter attached and the anus, and typically it only “sticks” when it’s soft) and lethargy/clinginess. Pretty general signs, however let’s focus on the diarrhea and assume it’s a GI thing. You didn’t tell me whether this is a cat or dog but I’ll assume dog since you said she goes outside to defecate.

Diarrhea may or may not be a sign of a serious disease. I don’t get especially concerned with one or two episodes in an animal who seems to feel completely normally otherwise, but what you’re describing sounds concerning. Your dog is restless, can’t get comfortable, and is somewhat needy – all of those indicate discomfort to me.

Without knowing how old your dog is it’s pretty difficult to get specific about causes, but I’ll mention some possibilities. Certainly parasites, including giardia, can cause diarrhea, as well as bacterial or viral infections in the gut. Indiscriminate eating, which dogs are master of, can cause diarrhea. Food allergies or sensitivities as well as inflammatory bowel disease are on the list. More serious causes include liver, kidney, or pancreatic disease, as well as intestinal cancers.

I’m hoping this has only been going on for a little while. You can try feeding a bland/high-fiber diet of boiled white meat chicken and white rice (25% chicken and 75% rice) in small (1/4 to 1/2 cup) amounts frequently (every two hours). If the diarrhea doesn’t resolve in 12 hours see a veterinarian. If she’s vomiting or won’t eat at all, see a vet sooner.

Q. What solid food should I start 4 week old Pit Bull puppies on?
ANSWER : A. A puppy food designed for large breed puppies can help with rapidly growing bones and joints and can be given in a wet form easily to puppies learning to eat solids. You can also provide a dry kibble for them to try and should moisten it with water or some formula to make it easier for the puppies to eat and digest. As the puppies grow and their teeth come in, they will begin to eat and explore more of the solid food on their own.

Mom should also be on a Puppy formula while nursing her puppies as it will provide extra nutrients to both her and babies while they are in a very rapid stage of growth!

Q. My 3 month puppy eats his own poop and is also biting what can I do to prevent this
ANSWER : A. When it comes to poop eating, you want to consider a few things. First off, what is his diet like? Maybe something is lacking in his diet that is causing him to want to eat his own poop. This is the most common reason why dogs eat THEIR OWN poop. Try a higher quality kibble like Taste of the Wild, Ziwipeak, Orijen.. and try feeding three meals per day, instead of the more common two meals per day. Remember to gradually switch his kibble. Add a little bit of the new kibble and reduce the old kibble very slowly.. little by little every couple of days until the bowl is mostly new kibble! You should also be cleaning up his poops IMMEDIATELY after he does them.. I mean like, you have a bag in your hand, and you are low enough to scoop it up RIGHT when he finished so he doesn’t have a chance to eat his poop.

When it comes to nipping there are a few things you can do. First, you should yelp as soon as the teeth touch your skin, stand up, cross your arms, and ignore the puppy until he is ignoring you. Once he is off doing his own thing, swoop down and calmly reward him by playing with him WITH A TOY so he doesn’t nip your hands. Whenever you pet him, or interact with him, you should always have a toy on-hand so you can give it to him. This toy should be a soft braided rope toy that YOU own. This means, your puppy is never allowed to have this toy on the floor, and your pup can never “win” tug games with this toy. This is YOUR toy that disappears when you’re finished playing, and reappears when you want to play. If you keep this up, in a weeks time, your puppy will be so excited to see that toy, that as soon as you bring it out, he stops nipping you because he wants to play with the toy. Another thing you can do is have two bags of toys. Bag#1 is full of chew toys/soft toys/squeaky toys/etc. After one week, Bag#1 disappears and out comes Bag#2. Bag#2 has the same types of toys as Bag#1, and it only stays out for one week. This keeps the toys feeling like new to your pup!
