Oh Hazel! Looking back, I wish I could turn back the hands of time.
Last Spring, Mollie weighed in
4 lbs over the 55 lbs threshold for both heart worm and topical flea meds so she was bumped up to the extra large dose, not having a clue about the ramifications. Meanwhile, I put her on a reduce calorie food to get her weight back down to her 50 lbs and believe she was being over medicated with a high volume of the Ivermectin combined with the Imidacloprid and Permethrin.
