Please help us.

Hello. My two pugs had fleas and we gave them both HARTZ flea and tick medicine. They were already upset about having fleas obviously, and then the next day one of them was acting fine and the other was acting a bit weak. About two days have passed, and one of them is still fine, and the other is continuing to act strangely. She hasn’t eaten anything we offer her and she doesn’t drink much. We’ve been trying to get her to eat and drink. Its not working.

On here, I read that we should use Dawn dish soap to try to get the stuff off her skin. We did that today, and gave her some Benadryl earlier. The vet said that its been too long since she received the HARTZ treatment and there isn’t much we can really do for her apparently.

Please, if anyone has any advice, please, please tell me.
I don’t want to lose a dog again. I just lost my childhood dog last year to a car and then got these two. I can’t take it, please, if anyone can, someone help us. She’s dying as I write this. 🙁
