Please see my avatar. His name is Stitches and he'll turn 18 in October. He was a rescue. Vet says he's probably a mixed breed terrier. Personally I think he may have some Llaso in him. He is bright, loyal and wonderful company. It has been the most wonderfully rewarding experience adopting a rescue. I would never do anything but now.
My favorite pure bred is an Olde English Sheepdog. I had two females, Sophie and Maggie. Lost Maggie to pancreatic cancer at 5, Maggie to lymphoma at 13. Very loyal, loving dogs. Sophie brilliantly smart. Maggie, ridiculously dittsy until age 3. Lots of grooming, need lots of exercise. Horribly prone to cancer.
Also had a basset hound Beauregard. Very kind and gentle but STUBBORN. Loved him to pieces but he tried every bit of patience I had, every day and in every way. Believe I had Beau for 12 years.
