Review: Effective Flea Prevention - My Cavalier King Charles Spaniel uses this and we have had no fleas or ticks all summer. No skin reaction to the topical solution. It stays a bit oily feeling and you can smell it for a couple of days, but it fades away and coat feels normal.
Review: Great flea protection - I take care of rescued dogs and this product works wonderfully on fleas.

### ⭐⭐⭐⭐⭐ Effective Flea Prevention
*by M***R on August 20, 2026*

My Cavalier King Charles Spaniel uses this and we have had no fleas or ticks all summer. No skin reaction to the topical solution. It stays a bit oily feeling and you can smell it for a couple of days, but it fades away and coat feels normal.

### ⭐⭐⭐⭐⭐ Great flea protection
*by E***A on August 16, 2026*

I take care of rescued dogs and this product works wonderfully on fleas.

### ⭐⭐⭐⭐⭐ GREAT PRODUCT.. Weigh your dog before buying...
*by A***N on July 23, 2011*

I want to start off by saying, price, product quality - genuine as stated - , seller is excellent and the shipping was FAST (free helps too).. Merchant = A+ Also the best way to know its the working or legitimate is when your dogs breathe changes following the treatment for a few days.. clear difference (depending on strength of product) _______________________ My review is a precaution for those like me stuck between 10 -11 lb dogs... (3-10, than a whopping 11 -20 lbs for the second size. The product works great which is why I work with this product only (this brand). The issue seems to be if you have a small dog its going to be well over 10 lbs in some cases.. so either I get a lower dose or the high dose (which seems to make their breath stink...its odd and happens with all small dogs (especially if its applied wrong) My only suggestion is: Weigh Your Dog Before Ordering Shipping: 3 days from order date arrived much faster than expected (big plus). My only downside: The product itself does not really take into account small dogs that are like between the two weight classes on the packaging. Seller: Excellent Contact Price: 120% OFF compared to vet (if you can figure that out!!) Thank you * Info @avalonpayments.com
