Pet's info: Dog | Chihuahua | Male | unneutered | 1 year and 2 months old | 3.75 lbs
We have been giving nacho revolution for heartworm and fleas (due to his small weight) with no treatment to prevent ticks. Our vet recommended switching him to simparica (2.8-5.5 lb.) since it is the only tick prevention medicine for his size. Have you had any experience with this product and would you recommend it? He’s a micro chihuahua- 14 months old and 3.75 lbs.
