I didn't know what to say when I read this first... I have had to put my puppy that I had for 16+ years and because I have been in the pet trade, I know that some animals have to be put down to spare them pain. I was ok when my mom made me drive her (my pup Sara) to the vet to get looked over because she was having issues. They did some test, and she stayed overnight there and they said she would have to be put down. My mom, dad, girlfriend, and myself went to go see her one last time. I was ok until my dad took her collar off. I still miss her all the time but she taught my other dogs, two German shepards, some of her manerisms. It makes it a little better when I go to my parents house to see my boy because his mama acts a bit like Sara.
I have to say the most sincere I am sorry for your loss. When my cat and dog had to be put down it was worse than some family members that has passed. I truly know your pain.
Sorry
Justin and Kate The Great
