Interesting... we assume Mogwai is a 9 week old Jack Russell cross. What the cross is up for arguement. I'm either leaning toward the fact she's older than we think (she seems far too well trained for a dog that young) or she's crossed with something slightly bigger than a Jack Russell but not too big. Some have been saying she has a Kelpie face and colouring.
For comparison she was:
The size of retriever puppies is terrifying...
The vet (who should know) says she'll probably double in size... which is still a very small dog...
