Diarrhoea in dogs, vomiting and loss of appetite can all be symptoms of many underlying conditions. All can be symptoms of worms, bacteria, food allergies, indigestible materials in the dog's system and a potential virus or illness. While there are home treatments for all these symptoms, the underlying condition should be determined through a veterinary visit.
Fasting for a 24-hour period can be a very beneficial home treatment for a dog with diarrhoea. It is important to encourage your dog to drink plenty of water during this period. Fasting might increase dehydration, therefore water intake should be encouraged. By fasting, you are ridding the dog's system of any harmful toxins or indigestible foods.
Vomiting in Dogs
If your dog is vomiting the first thing you should do is take away any remaining food or water she has access to. After the initial bout of vomiting and she has been stable (not vomiting) for more than an hour, you can slowly reintroduce small amounts of water and bland food (chicken broth and rice) to her diet. Home treatments such as these can be efficient in most cases, but if your dog is acting strangely other than the vomiting or if there is blood in her vomit, if her vomiting persists more than a day or if you suspect she has been exposed to poisons, you need to consult your veterinarian.
Loss of Appetite
A common reason for dogs to lose their appetite is heat. Often, especially in the Midwest when seasons change from bitterly cold winters to hot and humid summers, dog owners notice a large decrease in the amount of food and treats their dog takes in. In situations like this, where the dog is perfectly healthy yet has a decreased appetite, there is nothing you need to do--he will eat when he is hungry. However if he is exhibiting other symptoms along with his loss of appetite such as lethargic or fatigued behaviour, vomiting or diarrhoea, you should try a home treatment. Home treatments for loss of appetite should only be used when there are no other symptoms of illness in the dog. For example if the dog is stumbling or having problems chewing, there may be an underlying reason he is not eating.
If you are comfortable not seeking the treatment of a veterinarian, some home treatments to try for your dog's loss of appetite might be: give him fresh food in his bowl even if he didn't finish the food that was in there, make sure no one in the home is feeding "human food" to the dog as this will definitely make the dog food taste bad, and finally try sprinkling tasty treats on top of the food such as jerky or even wet food on top of dry food.
Other reasons for loss of appetite might be constipation, the dog doesn't like the food, depression and a change in routine at home such as recent move or new addition to the family.
Be pro-active in taking care of your dog's digestive system by feeding him a healthy, balanced diet. There are many different kinds of dog food, and it is important to feed your dog a diet with as few preservatives and additives as possible. There are also organic and natural dog foods available. Eliminate any access he has to compost piles, garbage or other harmful and toxic chemicals or substances.
