a 'new' 1 year heartworm shot??
My neighbor , who lives by the Mexican border either went 'over the border', or to a vet 'on' the border. She said the vet gave her dog a '1 year heartworm shot'. I am not aware of any such thing.
I am wondering if she was told Heartguard 6 was for a year..or what she may have been told...
If I am unaware of something, plz let me know, although I would not use it. Just wondering.
