I have had two dogs in my life. I had an Australian Shepherd and he was a great dog for children. He didn't have a lot of health problems until one day, he got very sick. My parents took him in to the vet and they said he had blood cancer and a tumor had burst or something and they had to put him down. He was about 9. We then got a miniature schnauzer from a very reputable and expensive breeder. She had tons of health issues, like arthritis, torn tendons, Cushing disease, acne, weird skin issues, etc. She got sick last week and, after numerous treatments, had to be put down as well on Friday morning. The vet thinks perhaps she had liver cancer. She was only about 10. So I am wondering: are we just unlucky or is this the new normal for pets? Are there dogs that will actually live 15 years and die relatively normal and peaceful deaths? My cat also died a traumatic death way before his time after extreme measures were taken to save his life. Obviously, I am heartbroken. I didnt live with her anymore because I am an adult, but I still loved her and had a strong bond from growing up with her. I'm wondering what kind of dog I should pick as an adult. I definitely think I do not want a purebred of any kind.
