Hi all. First post. Delighted to find a forum on Shih Tzus. I hope this has not been covered before. My wife and I bought a Shih Tzu from a reputable breeder in Ireland. He is an oversized Shih Tzu tipping the scales at 10.3 kg but he has been brilliant. Back is long but but beautifully balanced with a great tail and proud walk. We did the thoroughbred Embark test and we were quite taken aback to get a 10% Cavalier King Charles in his makeup. I have queried this with Embark and they are looking for additional information. Our Zeus is not IKC and when we did look originally it was practically impossible to get one that was IKC registered. The male line is definitely Asia but the female line has European ancestry. Question for the forum is - how common is it to get a mix in a Shih Tzu thoroughbred ?
