So today I brought Delilah to the vet for her DHPP and CIV boosters. She had her first set about three weeks ago. I was looking over the invoice and under "reminders" it says she needs DHLPP on 8/20/15 and then again on 9/13/15. I don't understand what this means. Does she really need the DHPP four times? If they wanted me to have the leptospirosis vaccine then why wouldn't they have just given me the DHLPP to begin with rather than bothering with the DHPP at all? I'm just wondering if this is a normal vaccination schedule for new dogs/rescue dogs/puppies. It seems really weird to me.
