Welcome to Pet Talk! What beautiful pups your Greta and Cassius are! I think Cassius definitely has some shepherd or one of the Belgium herding breeds in him...he's gorgeous regardless of breed! And what an expression on Greta's face! Precious! My name's Sandra and I have a 5 yr. old yellow Lab named Star and a red Husky, appx. 8 yrs., named Cody, as well as 2 kitties, Mr. B and Oliver and 2 guinea pigs, Moon and Rosie! I look forward to getting to know you and your beautiful furfamily!
