Hello, some dogs will drink a lot of water and then vomit shortly after from just drinking too fast. She could also have GI issues and would need to see your vet for prescription nausea medication such as cerenia. For dogs that are vomiting, you can also try chicken and rice to help calm her stomach.
A dog`s thirst is exacerbated when she is pregnant or nursing because she needs to increase her water intake. Dogs tend to drink heavily whenever their bodies need it.
Many conditions can lead to excessive thirst or dehydration in your dog, including diabetes, Cushing`s disease, cancer, diarrhea, fever, infection, kidney disease, and liver disease. Sometimes, however, it may not be the condition itself causing your dog`s excessive thirst, but the medication used to treat it.
Gastritis or gastroenteritis

Infections caused by viruses or bacteria can cause vomiting. Sometimes these are self-limiting, but others need medication. If your dog cannot keep food or water down, or if they are acting weak, lethargic, or otherwise unwell, it`s best to speak to a veterinarian.

Milk fever, also known as eclampsia or puerperal tetany, occurs when blood calcium is low after giving birth. It usually occurs within 2-4 weeks of whelping, but can also occur in the last weeks of gestation or pregnancy.
Pets will normally experience a fever for 24 to 48 hours after giving birth and may experience vaginal discharge for eight weeks. However, fever for more than 48 hours or foul smelling vaginal discharge,commonly signal metritis. Other postpartum complications may include these signs: Decreased appetite.
The clinical signs of more advanced kidney failure include loss of appetite, lethargy, vomiting, diarrhea, and very bad breath. Occasionally, ulcers will be found in the mouth.
When dogs become stressed or anxious, they will often pant and sweat more, causing greater loss of water than just through urination. To replace the fluids they lack, they will drink more water. A stressed dog may also urinate inappropriately.
In many cases, your dog will be treated with anti-nausea medications, antacids, and/or GI protectant drugs to provide relief. Your vet may opt to administer the first doses in an injectable form to avoid further vomiting.
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.
Dogs sometimes vomit up yellow foam. This yellow foam is a form of bile, or digestive fluid, that is produced in the liver, stored in the gallbladder, and released into the small intestine, just below the stomach. This yellow foam usually means that its stomach is empty and the bile is causing stomach irritation.
After the birthing process, clean up the mother as much as possible without upsetting her using a warm water and washcloth. Do not use any soaps or disinfectants unless instructed to by your veterinarian. Remove any soiled newspaper or bedding from her whelping box.
Once a dog gives birth to her puppies, two different hormones contribute to her motherly instincts. The first is oxytocin, sometimes called the “love hormone.” It`s what drives a mother dog to nuzzle her puppies or wrap around them to keep them warm while nursing.
It`s an instinctive thing, an evolutionary trait that surfaces from time to time. They`ll eat a puppy when they see it as waste material. A dead puppy, or a sick one, will – in their perception – make the rest of the litter sick and / or weaken the chances of the group`s survival.
Certain products can help boost milk supply if your dog seems to be struggling. Milk thistle is one natural supplement known to help nursing mothers with their milk-making. Other dogs benefit from taking zinc while providing for their pups. In small doses, apricot can also increase milk production.
While panting immediately after birth is a completely normal occurrence, prolonged panting is not. If this issue continues for several days after delivering puppies, your dog may be experiencing problems such as: an incomplete birth, milk fever, a high temperature, heart problems, or pain of some sort.
Many breeders encourage food intake by offering highly palatable products, such as ice cream, homemade mixtures (for example, mix one can of evaporated milk, one can of water, three egg yolks and one-quarter cup of Karo syrup; heat, then let cool), puppy-milk replacers or a growth-and-lactation commercial cat food.
Typically, green urine indicates late-stage kidney failure, cancer of the kidneys, or extremely severe urinary tract infection. Urine may turn green because bilirubin makes its way into the kidneys, where it is not supposed to be.
Bad breath – Breath that smells like an outhouse can be seen in the advanced stages of renal failure in dogs. This is a result of the toxins that build up in the blood.
Often bladder, kidney, or liver problems are what causes excessive thirst and urination in dogs. In fact, dogs may be responding to any number of bladder problems that make the sensation of urination quite urgent, even when it`s really not. These can include: Bladder infection.
Excessive drinking can be the result of a walk in the summer heat as well as an indication of serious illness. If your dog has diabetes or an inflammation of the bladder or uterus, it will have an increased need for water. Painful kidney disease, for example, can also be a trigger for your dog to drink a lot.
An increase in hunger may be accompanied by an increase in thirst. Weight can be gained or lost despite the hunger. These changes, as well as other signs of trouble, may indicate health conditions like diabetes or parasitic infestation. Any change in appetite should always be investigated by the veterinarian.
Take away her food bowl and remove her water bowl, as well—guzzling too much H20 can irritate your pup`s GI tract even further. Instead, offer a few laps or ice cubes every few hours, suggests Elswick. “Gently rubbing his or her abdomen when your dog has an “upset tummy” may provide some comfort,” says Elswick.

the most relevant questions and answers related to your specific issue

Q. My dog drinks a lot of water, should I worry?
ANSWER : A. Firstly, you should quantify if your dog is actually drinking an excessive amount of water. In a 24 hour period, a dog should drink about 1 fluid ounce (or 30mL) per pound of body weight. Therefore, the recommended amount of water intake (in fluid ounces) equals your dog’s weight (in pounds). For example, if your dog weighs 8 pounds, he/she should drink about a cup of water in a 1 hour period. This will be slightly increased if your dog gets a lot of physical activity or lives outdoors.

You can measure your dog’s water intake the following way: in the morning, measure a specific amount, a little bit more than you think he/she will drink. 24 hours later, measure the remaining amount. If the amount of water your dog drank is significantly greater than it should be, then you should take your dog to a veterinarian.

Causes for mildly increased water consumption include: food changes, increased ambient and body temperature, increased activity, urinary tract infection, and general illness.

Common causes for greatly increased water consumption include: diabetes, urinary tract infection, kidney disease, steroid use, and other systemic diseases. With large increases in water consumption, you will also usually see increased urination. Please take note of urinary patterns to discuss with your vet. Greatly increased drinking and urination is ALWAYS a reason to see a vet.

Q. My dog throws up after drinking water, what should I do?
ANSWER : A. If this only happens occasionally (a few times per week or month), and your dog throws up just water, it is not usually an emergency. Consider your dog’s activity before the event – physical activity, stress, elevated temperature, drinking too fast, and inhaling water can cause them to vomit water. Try elevating the bowl, giving him/her small amounts of water at once and waiting a few minutes after the activity.

Even if this has only happened once, if your dog is acting strange afterwards (low level of activity, not eating, etc.) you should visit your veterinarian immediately. Vomiting can be a sign of an obstruction, heat stroke, or a multitude of other causes.

If this happens frequently and you cannot figure out the cause, your dog should also be examined by a veterinarian. Chronic daily vomiting can be a sign of many problems, including a chronic obstruction, other gastrointestinal disease, or a systemic disease.

Q. My dog just puked on the tile and layer around. He then proceeded to get up and drink 4 bowls of water. Why did he drink so much water?
ANSWER : A. He was feeling thirsty because he has lost lots of fluids with the vomit and his body was telling him to increase the water intake. It’s normally a good idea to start offering small amounts of water little and often, otherways if the stomach is still upset, too much water can cause the vomiting to occurr again.

Q. Can I give my dog ice water to drink?
ANSWER : A. Yes, of course you can. However, you do not want to give ice water to your dog when he is already overheating. If your dog is panting, shallow breaths, vomiting, displaying gums of a different color, having diarrhea, or lethargic, do not give him ice water. Ice, ice water, and very cold water all shock your dogs system, and constrict the blood vessels, making your dog hotter in-turn. It could turn deadly.

If your dog is acting normal, and in a cool room, feel free to give him some ice water, or ice cubes! There a fun treat, and you have nothing to worry about. It’s truly only when they’re very hot, or overheating.

FYI, if the dogs are vomiting, panting with shallow breaths, having diarrhea, etc.. please see a vet immediately.

Q. My three month puppy is teething and she’s biting everything. What can I do?
ANSWER : A. As you know, this is a normal issue to have with a 3 month old puppy. Be sure that you are never scolding your pup for biting/nipping/teething. This is so natural and normal for them, scolding gives very mixed messages. There are a few things you can do to help teach your pup that nipping on you is inappropriate without the use of scolding.

First off, you should have a toy that YOU own. This toy should be brand new. It should be something like a SOFT braided rope toy. Never allow your pup to play with this toy without you. Never leave this toy on the ground for your pup to play with. Never allow your pup to “”win”” tug games with this toy. This toy disappears when YOU are finished playing with it. This toy is hidden from your pups sight whenever you are finished playing with it. After about a week of keeping this toy hidden from your pup, and only bringing it out when YOU are engaging your puppy in play, you can THEN begin to use it to redirect your pups attention when she nips.

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. He ate grass yesterday morning. He is drinking a lot more water than usual and vomits all the water he just drank almost immediately after.
ANSWER : A. Limit the amount of water he drinks, otherwise he will keep vomiting.

Starve him for the next 8-12 hours, then feed him with bland diet (boiled chicken and rice) in smaller portion every 3-4 hours.

If he does not improve in the next 24 hours I would suggest to take him to your veterinarian for a check up and appropriate treatment. If you want to discuss it further please request a consult.
