I like the new dog, but if she gets my baby killed, I'm going to be . . . I don't even know. :(
EDIT:: Apparently I was given some bad info by the vet tech. Now that I know the heartworms are only transmitted by mosquito bites, I feel much better. Thanks to everyone who commented letting me know that.
And, no, I'm not blaming the new dog. I know she can't help it.
