Gastrointestinal.
A common problem for pets is vomiting and diarrhea. Any vomiting pet must be evaluated for dehydration. If your pet is profusely vomiting ( ie every few hours), then they are getting dehydrated and need veterinary care. If your pet is still consuming water and occasionally vomiting, then you can try some of the home remedies.
Two home remedies that are effective include HOMEOPATHIC and HERBAL remedies.
Nux Vomica is an effective homeopathic remedy for vomiting. Give 1 tablet of the 30C strength per 40lbs once daily for 3-5 days.
GINGER. A tasty addition for a curry is also effective for vomiting. The dried herb dose is 25mg per lb or 1 drop per lb twice daily of the tincture
Diarrhea can be caused by a number of different things, from garbage, to parasites, to infectious agents (such as parvovirus). Most cases of diarrhea respond to symptomatic treatment at home.
The most effective one is 24 HOUR FAST. Stop putting food into your pet for 24 hours (Day 1). This allows the intestines to rest and regenerate. Always have access to plenty of fresh water. After 24 hours introduce a bland food for the next 24 hours (Day 2). Plain white cooked rice for dogs, feeding equivalent cups of rice as their normal diet.
