Very sorry to hear you lost your four-legged chum. I hope friends, family, and fond memories give you some measure of solace.

Perhaps to be expected coming from the manufacturer. That applies to human medicines as well as pet medicines.

So sorry you went through this. It is hard to say goodbye to our pets and even harder when it is due to a medication that shouldn’t be available.

Do pet medications require approval by the FDA?

I sympathize with you. My 24 year old niece now has to live with moderate heart damage after a "safe and effective" injection she was compelled to take a few years back (my brother is still angry and bitter, justifiably). She says her GP just shrugged when she was referred to a cardiologist. Why? My guess is because the FDA had approved that one too.

After that, my family have all agreed: no injections for anyone or any pet ever again, come what may. Your and Berkeley's terrible experience only solidifies the decision.

Thank you for rescuing Berkeley, you gave him many (but still too few) years filled with love.
I am so sorry for your loss, and I will avoid using this drug for our EB Atticus. He is turning 10 this month.

I'm sorry.to hear that. They are family members.
We fought our vet on Heartworm treatment, years ago, and went with an unconventional treatment. The vet said it would kill our dog, but the traditional Vet meds would have killed her, because she was so active. End result, she is alive and happy. The Vet admitted our treatment worked, and looked stupified, when admitting it.
BTW, she.was on Hearguard when she got Heart Worms. I've had two dogs get Heart Worms while on that stuff.

Wow! Can you share the unconventional treatment?

I believe it was a simple antibiotic(Doxycycline) and heatworm preventative(Advantage Ultra). I will have to have the wife look up the dosages. It was a few years ago. I remember the vet having us sign a form releasing them from responsibility.
