Okay, I'm confused and I'm struggling like you Crystal with how to deal with heartworm and ticks (flears are not a big issue around here). I just did an internet search on Revolution and it says it's a topical treatment (like Frontline), not an oral treatment. Did your vet give you pills or vials like Frontline?
On this same subject, I just got off the phone with one of the new puppy owners. They were concerned because they gave Teddy Heartgard yesterday, he vomited this morning, wasn't much interested in food and didn't want to play. Why do people not listen??? I specifically said I would not give Heartgard to a puppy that young (5 mos. on 6/5) and that small (4 lbs.) since the smallest dosage is good for dogs up to 25 lbs. :smilie_tischkante: Thankfully they called the emergency vet, and magically he perked up while they were on the phone. Part of the disinterest in food is probably also that he is teething (the others are starting to get some adult teeth now) and to soften his food with water and microwave it for 20 seconds. So what have they beein doing? Hand feeding him chicken and cheese!! It will all work out, I'm sure, but until then .... I'm biting my tongue and it's starting to hurt!
