My Jack Russell Isn't Growing!
I've had my beautiful jack russell - Minnie - since october and she's about 8 months old, but is still absolutely tiny. She's about half the size of one of the Jack Russells on the yard, who is considered relatively small. I can pick her up with one hand and she's the same size as a ten week old border terrier pup! Not sure of her measurements, but she is tiny, could there be any reason for this? Her mother is small, but nowhere near her size, and all the pups in her litter were the same size at ten weeks. She is also completely reddish/brown with no white on her, despite both her parents having brown, white and black colouring. Help?!
