yeah, i feel for ya. we had to put my shepherd/boxer to sleep cause he had heartworms. that dog was so damn smart, he was fast too. once i saw him catch a bluejay mid-air, then he ate it. it was bad ace. no we have a yorkie. hes nice but like stan's dog has anxiety issues. that fugger wont let you leave the house.
i hope you get another real soon though. get a german shepherd, they rule, or a lab.
