My 25.3 lb dog: What Heartgard Plus dose if weighed with collar?

She can get the 26-50 lb dose. Heartgard has a wide margin of safety so the larger dose is recommended. It it a better option than potentially underdosing Pudding. You should discuss further concerns with your veterinarian.

Good for you for taking some weight off Leila to help with her hips! I know that can be challending. In general, the amount of ivermectin in Heartgard is very low, and it is not a problem for a dog that is just under 50 pounds to have the 51-100 pound dose. However, some dog breeds are sensitive to ivermectin, so I would certainly ask your veterinarian about their recommendation for Leila just to be on the safe side. Good luck! I hope that was helpful.

You should give him the appropriate size. If you don’t give him the appropriate size you don’t get the full course of action. You may talk to your veterinarian and see if they can exchange the product for you. All clinics that have different policies. Please feel free to post any additional questions.

Yes, you can give Fern two doses of the Heartgard so that she will get the correct amount of medication. Heartgard is a pretty safe drug, and you would need 10 to 20 times the recommended dose to see toxicity; however, in this case, because two of the chews from the green pack equals the same amount of medication in one chew from the brown pack, it's safe to give to her. I hope this helps!

Sentinel has no tick coverage and does not kill fleas. It only sterilizes the eggs. I always go up a size to be safe as most dogs gain weight but rarely lose weight. It has a good safety margin so using the 25-50 pounds medicine would be best. You will continue to need the Simparica or nexgard with this

Yes! These medications are based on weight and this is usually the manufacturer’s recommendation. If your dog is a little overweight this might be an incentive to get him under 100 lbs. Heartworm is a serious disease and the cost of treatment would by far exceed the cost of the extra pills.

She'll probably be fine for this month if she's just a pound or two over. But in the future, if she's gained a bit of weight and is now borderline or just over the maximum weight for her current dose, I would get the next size up. Nexgard has a very wide margin of safety, so the manufacturer recommends "rounding up" if a dog is near the upper limit of the weight range. :)
