What is Dehydration?

Canine Dehydration:

Dogs, much like people, require water to ensure their bodies are working properly. Water is so important, in fact, that essentially all bodily functions require it to remain healthy and operative. If your dog loses more water and electrolytes than they are taking in, they will begin to dehydrate, and their health will deteriorate.
It's important to understand that dehydration in your dog can lead to kidney failure, unconsciousness, and even death in extreme cases.

How to Prevent Dehydration in your Dog?

You should contact your vet if your dog is suffering from severe or continuous vomiting and/or diarrhea, so they are able to examine your pet to determine the underlying cause. Many serious health conditions may present with symptoms of vomiting and diarrhea, all of which require immediate medical attention. If your dog is experiencing these symptoms, try to offer them an electrolyte solution to replace lost minerals and maintain their fluid levels until they recover. IV fluids may become necessary if the symptoms persist to prevent dehydration.
Always provide your pet with an ample supply of clean drinking water to prevent dehydration. If your dog spends time outdoors, especially in hot weather, or has had a lot of exercise, they will need extra water to replace what has been lost.
