## Description

Product Description

Review: Great - Great product. I care for several stray cats so i buy this XL dog product and divide it up into six cat doses. This particular product is not too viscous and easy to pull up with a syringe and also doesn’t smell strong. Works well as well.
Review: For golden retriever - My dog golden retriever who is one year old was suffering continuously for lice and flea’s. With this spot on he got rid of lice completely. My dog is having weight of 33 kgs but I am using spot on 4.09 ml for better result.

### ⭐⭐⭐⭐⭐ Effective and worth buying
*by A***A on 18 November 2025*

It has worked really well for my dog. I started it to help with recurring ticks and fleas, and within a short time the constant scratching reduced and his skin looked calmer. It’s easy to use and doesn’t have any strong smell, which is a relief.
