Review of Certifect for Dogs 3pk Large 45-88lbs Flea/tick Topical

Customer Ratings:

I purchased this item today from the vet since my dog has been getting Tics and frontline does not appear to be working. I put it on as directed and it has left a strong odor. I put it on my dog 3 hours ago and the toxic smell has permeated my entire house. My dog is usually happyenergetic, wags tail, playful, etc. Since I put it on he has followed me around the house only sleeping. The box says a side effect can be lethargic. this product has encouraged me to finally seek natural products, i buy organic non pesticide products for myself, why not for my dog. I would not recommend this product.

Took too long to get. Cost too much and was not an improvement over other flea and tick products. I would not recommend.
