i have a 3/4 whippet 1/4 beddy bitch, she is 3yrs old now and 20tts, she has great feet and unlike what alot of people say, she hasn't had any bad injury or skin rips, she doesn't have a thick coat but it's tight (if you know what i mean). she is great at ferreting, lamping, caught a few big rabbits daytime and will tackle things that bite back, if there was anything i would like her to have it would be a few more inches, other than that she does me, there is one thing about these wee dogs, they can and will punch well above there weight.
