I took Hiro to the vet last Monday to get some Heartgard. It's been really hot and dry so she's been inside for the most part. Well, they did the test, and it turns out she's positive for heartworms. We've only had her for about six months and the vet said they're pretty bad, so she's had them since before we got her. I was so disappointed. I guess the shelter that we got her from either didn't catch them or didn't even test her. I also feel bad that I didn't take her sooner, but I didn't have the money, and I just thought that since we adopted her they would've tested her. But She's got a week more of doxycycline then she's going in for her treatment. She's such a high energy dog, so I'm gonna feel bad about having to crate her after the treatment, but I know it's important! I'm just asking for you guys to send good wishes her way!
