Definitely dogs. My first dog, Teddy lived 18 years. It was like losing one of the family when he died.
Rocket was my wife's dog. He had cancer and i held him while the vet put him to sleep. His pal,Bugsy, died six days later of a broken heart.
Vinnie the Pooh was my daughter's first dog. She was a Russian orphan and Vinnie taught her how to love again. She still keeps his ashes by her bed.
Frankie Blue Eyes came along after Rocket died. We almost lost him when he reacted badly to a routine vaccination.
Jackson followed Vinnie and currently sleeps with my daughter.
I still have Reggie, our only female dog, but she is getting old.
