Hello, I just recently became aware of TM breed and am very interested in it. I rescued my dog as a puppy nearly 12 years ago. I have never had any idea about what breeds are in his genetics, as his papers at the shelter simply said australian shepherd mix. I first encountered a TM about three months ago while vacationing in California and have spent time since researching them. I believe my dog has gold/black TM heritage. Ive included pictures for you to judge whether he is part TM or not. he weighs 65-75lbs and is about 24 or 25 inches to the shoulder. on a side note, I am curious if anyone would be aware of TM breeders near San Luis Valley, CO, as that is where my dog was born. Thank you, please leave feedback
