Dehydration:

Dogs rely on water just like what humans do to keep them healthy and functioning properly.

Water is critically important to every organ and also assists with digestion. Your dog is panting and urinating throughout the day and needs to replace the liquid he loses.

Dehydration in dogs results in loss of electrolytes, such as sodium, chloride, and potassium.This is bad as these minerals have important functions.

A dog that is dehydrated has loss of appetite, loss of skin elasticity, is lethargic, has sunken eyes, wants to vomit, has a dry nose and thick saliva. No dog should ever be left without a constant supply of fresh, cool water day and night.

Exercise:

The Jack Russell Terrier isn’t just a small dog that can be left to his own devices. He will need proper training and socialization early in life to make him obedient and better to get on with.

This dog will do well with some raw meat added into his diet. Also, include home-made food too. Boiled chicken, brown rice or pasta, sweet potatoes, carrots and spinach chopped up and added to his dry kibble for giant breeds. Added in twice a week can do him the world of good.
