## Description

Tell pesky parasites to ‘bug off’ with the Hartz UltraGuard Flea & Tick Collar for Dogs and Puppies. This fresh scented, white collar kills and repels fleas and ticks on pups with necks up to 20 inches for 7 months. The water resistant design remains effective even after playtime in the rain. For continuous flea and tick protection from head to tail, replace the collar every 7 months. Directions: Remove collar from package, unroll and stretch to activate insecticide generator. Do not use on puppies under 6 weeks of age. Do not unroll collar until ready to use. Place the collar around the dog’s neck, adjust for proper fit and buckle in place. The collar must be worn loosely to allow for growth of the dog and to permit the collar to move about the neck. Generally, a properly fitted collar is one that, when fastened, will snugly slide over the dog’s head. Leave 2 or 3 inches on the collar for extra adjustment and cut off and dispose of the extra length. Consult a veterinarian before using this product on debilitated, aged or medicated pets. Sensitivity may occur after using any pesticide product for pets. Some animals may become irritated by the collar if it is applied too tightly. If this occurs, loosen the collar. If irritation continues, remove the collar and bathe your dog with mild soap and rinse with large amount of water. If signs continue, consult a veterinarian immediately. Do not use this product on dogs simultaneously or within 30 days before or after treatment of other flea and tick products. However, flea and tick collars may be replaced immediately.

Review: Must buy! - Works great for both my dogs and they never got a single tick or flea on them this past year. Will be buying some again in the spring! A lot cheaper than the pill or liquid form. My mom and dad always swore these collars that's the only way to go. I'm a true believer now.
Review: Tick be gone! - Works great. My dog hasn’t had any ticks with this collar on him. Highly recommend

### ⭐⭐⭐⭐⭐ Tick be gone!
*by L***N on February 2, 2026*

Works great. My dog hasn’t had any ticks with this collar on him. Highly recommend

### ⭐⭐⭐⭐⭐ Works great, just stretch the entire length first to activate before putting on animal.
*by B***. on December 21, 2025*

I keep one of these on each of my outside dogs and they never have any ticks or fleas on them. Just remember to stretch it out a little to activate it before you put it on your dog. The first time I put one I overlooked this and was wondering why it wasn't working all that great then I got another and read the box and seen where it said to stretch the entire length first to activate after that no problems works like a charm.
