No they are not. If You ever saw adult jack russells and jack Russell puppies about eight weeks of age or older they would normally have short tails. But when a jack Russell is born its tail won't be short as in the fully grown jack Russell or older jack Russell puppies. Its tail would be long. And to make it short the jack Russell puppies have to get their tails docked which means their tail would have to be cut partly off. But never do this yourself! If you have a female jack rusell and if she had puppies please be sure to take the puppies to the vet so the veterinarians can dock their tails. But before you go please be sure to take the mother with you so she see whats happening to her puppies. But remember, the jack Russell puppies' tails have to be docked before they are three days old otherwise it would hurt if the puppies get their tails docked to late.
No, they can only have jack russell puppies. Now if you had asked if a jack russell dog can eat crisps, that's a totally different question...
