My dogs:
Sonny the bull/whippet/greyhound, as a sapling:
Gypsy my Sealyham/bull/Russell bitch at around 2 years old:
Both work, and the terrier especially would love to 'meet' most of the animals pictured in this thread. Unfortunately she's got quite a knack for cats and pet rabbits, as my Mrs discovered
Still, she likes her earthwork and bushing/ratting, and does us well. Sonny's only just starting really, but has already shown good promise in the field.
We also have pythons (Jaguar Coastal Carpet, Albino Royal) and a menagerie that once consisted of a rabbit and a cat
Oh, and two ferrets (for rabbiting, never tried them on rats as they bolt easily enough round here anyway).
