Chipping your pet always seems ridiculously overpriced when you first do it. I know the sticker shock all too well - 2 animals at the same time, ouch! (add this to a spay and neuter, ugh!)
Explaining to your wife and kids after a pet goes missing why you didn't costs a lot more. Kicking yourself around for it does, too.
And if your dog is an expensive breed, why wouldn't you? It's a lot better when you get your buddy back.
Glad to hear Lily got home, safe and sound. Thanks for being a Good Samaritan, dieseldoctor
