Will it hurt to give a 35 pound dog a heartgard heartworm pill for dogs 51-100lbs?

I have two dogs one is around 35 lbs and the other is 60lbs. I usually buy different sizes of heartworm pills and frontline treatment. I was just wondering how important following that was. would it work if i gave my 60lb dog a heartworm pill for dogs up to 50lbs. I dont want to hurt either of my dogs.

Yes, the dosage is too high and you may harm your dog. The doage is based on weight.

Is Nuheart (or other generic heart worm preventatives) as good as Heartgard for dogs?

Trying to save some money, but keep my dog healthy. Anyone who has used these before, or has any real knowledge please let me konw. Thanks.

Look at the labels, if the generic has the same active ingredient/s as Heart guard, then they are basically the same thing. Just like Generics or store brands for people.

I get heartgard for my dog, now it is 30.00 for 6 months. Is the generic brand o.k. after 2 refills my vet wants to do blood work, plus exams. I want to best for my dog but also need to save if I can

Generic drugs are held to the same standards as brand name drugs (as far as active ingredient and safety). If your vet is recommending a generic, go ahead and use it.
