How to treat a lame dog.

When dogs frequently vomit and have diarrhea, it may also lead to lameness, which is related to the electrolyte balance in the dog's body. Vomiting and diarrhea will cause a large amount of dehydration in the dog. When the supplement is not timely, the amount of sodium ions, chloride ions and other ions will decrease, causing the dog to become lame. With such lameness, the dog will also have obvious muscle tremors and weakness. At this time, parents need to give their dogs appropriate energy and water first, and then solve the original causes of vomiting and diarrhea in dogs. If the situation is more serious, you need to go to the hospital for infusion and replenishment.
