Please help - I am wracked with guilt.
I'm sorry, but I can't help with the heartworm symptoms.
Hi firesmom....and I'm sorry I didn't see this post sooner.
Firesmom, I just wanted to check in and see what the vet was able to tell you. If it's heartworm, the important thing now is just to start treatment for him. If you have trouble remembering her heartworm preventative, maybe set a calendar reminder for yourself in your phone, Outlook, etc. I hope everything turns out well.
