She looks like a yellow Lab mix. I could see her having Pit Bull, অথবা some type of bully breed, in her makeup, due to her heavyset build and barrel chest. As a mutt, she could have some ক্ষুদ্রকায় কুকুর (fairly likely) অথবা even shepherd in her lineage too...
She ব্যক্ত herself in one episode that she is a mutt. She appears to have pit ষাঁড় in her, she even ব্যক্ত so herself, and definitely some labrador, due to her coloring.
It is established in several episodes that she is a mutt, but it doesn't say what breeds are in the mix. Truman: I wish I had a bloodhound. He could help me find what I lost. Martha: I'm a mutt, a mix of breeds. One could be a bloodhound.
