It is sad that God only gives 10-20 years on average for our pets, but it teaches us about life and how things depend on us for survival. I am more of a cat person but let the wife have a couple Labradors that were awesome, they only last around 12 years. Our cats have lasted pretty close to 20 years each, and now have three two year olds that should last us until we are gone. RIP Prissy...
