but how do

A. If you think he has been poisoned you need to contact your vet immediately as the quicker you receive treatment the more likely that you are to get a good outcome. They will be able to run blood tests to see if the kidneys and liver are functioning properly. These are the normal organs that are affected by toxins.

How to Identify Common Pet Problems ?

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

Clinical signs of poisoning in a dog may include: Gastrointestinal signs: vomiting, diarrhea, extreme salivation, loss of appetite, and nausea or dry heaving. Internal bleeding: indicated by pale gums, a racing heart, coughing up or vomiting blood, weakness or lethargy, or a dog`s falling over or collapsing.
2) Stops Eating/Drinking

This is due to the beginning of their organs shutting down. They no longer have the sensation of hunger or thirst. You can try to keep them hydrated by giving them water in a dropper or turkey baster. But if they won`t swallow it, there`s not a whole lot you can do.

It is common for dogs to lose their appetite in their final days, particularly if they are experiencing nausea or pain.
Your dog may vomit after eating something harmful, but it`s more likely that symptoms will take a couple of days to develop (depending on what they has eaten). Contact your vet immediately for an emergency appointment if you think that your dog may have eaten something harmful.
Not surprisingly, chemicals contained in antifreeze, paint thinner, and chemicals for pools also can act as dog poison. The pet poisoning symptoms they may produce include stomach upset, depression, chemical burns, renal failure and death.
Affected dogs show signs 30 minutes to 4 hours after ingesting the poison. Initially affected dogs become anxious and have an elevated body temperature. Panting is usually seen. Progressively they become worse and staggery.
Signs a dog is actively dying include labored breathing, an inability to control their bowels or bladder, a refusal to eat, and a lack of reaction to stimuli. Slow movements, a change in appetite, increased sleep, and a decrease in social behavior could be signs that your dog is just aging normally (and not dying).
Dogs need food and water to survive. However, if they are otherwise well, they can survive for around 5 days without food, as long as they are drinking. It`s true that dogs have survived for much longer periods without food, but there is a great risk of irreversible damage to their organs and tissues, or death.
Chronic illness may cause dogs to stop eating but continue drinking. If your dog is avoiding food but is drinking excessive amounts of water—much more than is normal for him—this is a telltale sign that he has develop diabetes. Take him to the vet for a diagnosis and to find out more about his options.
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.
Dogs usually have a healthy appetite. However, it becomes quite challenging to feed them when they become ill, as they have reduced appetite and upset stomachs and might not eat the food they usually like. Your dog needs special food when they get sick, just like people do.
Illness or Injury

Canines may also hide if they are feeling unwell. If your dog starts hiding on a regular basis with no apparent provocation, particularly if it is combined with lethargy, loss of appetite, indications of pain and discomfort, retching or vomiting, a visit to your veterinarian may be a good idea.

Excessive bruising, bleeding, sores, and burns are signs of external poisoning or caustic substances. This may be the result of plants or chemicals. If you think your pet has come into contact with such a poison, be sure to try and remove toxic substances from the area as soon as possible to minimise irritation.
25% of poisoned pets recover within two hours. Of the pets that take longer to recover, many can be treated at home with the advice of your veterinarian or with advice from the ASPCA Poison Control Center (telephone 1-888-426-4435). Even with treatment, one in 100 poisoned pets dies.
Swallowed poisons, for example, often cause sickness, diarrhoea, agitation and heart issues. If your dog has inhaled something toxic they may find it difficult to breathe or lose consciousness. Poisons that come into contact with your dog`s skin can cause irritation and pain.
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.
If your dog died unexpectedly at home, you can contact your veterinarian for advice, but it`s probably easier to go directly to a pet cemetary or a crematorium. Either way, you`ll have to transport your pet to their facility.
He has lost interest in all or most of his favorite activities, such as going for walks, playing with toys or other pets, eating treats or soliciting attention and petting from family members. He cannot stand on his own or falls down when trying to walk. He has chronic labored breathing or coughing.
Dogs have several reasons for staring at their owners, like to communicate with and understand us. Some dogs stare to manipulate owners, as in with begging for food or asking to be let outside. Training and dog sports are good ways to turn focused staring behavior into a positive experience.
The digestive system is the first to be affected. When the dying process begins there is a loss of appetite and thirst. The brain will also lose function and shut down. This is due to a lack of oxygen attributed to labored breathing and the eventual cessation of breathing.
The Danger of Death Sign is a hazard warning sign. Depicted by a yellow triangle, with a black surround, a pictogram of an immobile figure and a downward pointing flash. These signs are used on building sites, industry and workshops to alert employees and visitors of significant danger.
The short answer is that dogs can survive between 48 and 72 hours without drinking, but that doesn`t really capture the whole picture. Survival is a minimum and a dog allowed to drink only once every 2 days would be the subject of cruel abuse.
Should You Force-Feed a Sick Dog? You can use a syringe to force-feed your dog if it has been more than 48 hours since your dog ate. This should only be done after your veterinarian has examined your pet and determined force-feeding was okay.
Ginger. 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.

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. 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. Dog wont eat or drink have been giving pedilyte fluids every 2 hours dint know if it is poisoning or something else
ANSWER : A. If you think it is poisoned then you need to see your vet or emergency vet immediately as the sooner it is dealt with the better chance of a good outcome.
You can try tempting to eat with some cooked chicken served warm as this can encourage eating. If your dog has been like this for more than a day then you should see your vet as soon as possible to have some blood tests and maybe some intravenous fluids.

Q. My dog will not eat dry or moist dog food, buy bag after bag and have tried little ceasers moist food and she will not eat that either.
ANSWER : A. Dogs are like children. They won’t eat the healthy stuff if they think they will get something better. Unless there is something wrong with the dog eg vomiting etc then they will eat when they get hungry. You need to only offer the food for a week. Put it down if not eaten within an hour take up till dinner time. Do this every day and don’t give in as dog needs to be very hungry and realise wont get anything else. If has any ill symptoms then you should see a vet first.

Q. hi my bird salivated a bit and its i think because i forced her to eat i am really worried about her
ANSWER : A. If you are having to force your bird to eat, that is already a big sign that she is not feeling well. If you are seeing drooling/salivation in addition to refusal to eat or lethargy, it may indicate a serious illness. Birds are good at hiding signs of illness, so it is best to seek veterinary care ASAP if you are already seeing them. In the meantime, keeping her in a hospital cage that is warm and away from other birds (if you have them) is best to let her rest and recover some until she can receive treatment.

Q. What brand of dog food should I feed my dog? She’s a husky mix and about 45 lbs. She’s almost 2 years old.
ANSWER : A. I would recommend Natural Balance at your local Petco store. Call the store and ask if they have a Natural Balance Brand rep who comes to the store and see when they come. Make sure the brand rep brings free samples with them. Normally they bring samples of the different flavors to the store and you should ask for some to try to see what your dog likes best. Offer the dog the different kibble and see which they prefer by holding them out in your hands and switch out the flavors. My dog prefered the Salmon based Natural Balance Synergy bag the best from all the flavors. I also found out he doesn’t care for the Bison Natural Balance even though a lot of dogs love it. The Petco may have free samples already so ask if they do. The pet store associates should be able to also assist you in finding the right food for you. The reason you want to go with a high quality high protein food vs the cheaper brands because they are grain free, no by products, and no corn. The cheaper brands have corn in it as the main ingredient and by product which is also very bad. When our dogs are forced to eat the cheaper brands they have to eat more to get the energy they need from the food resulting in more bowel movements and without the proper nutrients this can hurt their health later in life. The higher quality brands will be more cost per bag but you will be buying less because the dog eats less so you will be saving money that way and it comes out about even in the long run. Petco has a great Rewards Program so make sure to sign up and ask about the details on it. Every $100 you spend you get $5 in your email with the Pet Pals Reward Program.
