Although it’s usually hard to know for certain whether you’ve got a purebred dog on your hands unless you’re the breeder yourself or there are certificates of authenticity to be had, there are some telltale signs that indicate a full Australian Shepherd x Australian Shepherd born puppy.
For instance, an Australian Shepherd will have a bobbed tail that’s thicker and bushier than average – they will also usually hold their tails at head height, with a visible arc.
You should also try to look for any natural herding instincts or behaviors from your puppy, as these are surefire signs of Shepherd genes.
Likewise, they should also be especially protective of you and the rest of the family, with a tendency to overdo the whole guard dog role.
