Q: Will this collar stay effective if worn in water? Looking for something for my dog that also loves to swim in a lake!
submitted by ElleDub - 2 years ago
A: The collar is water resistant. Wetting the collar will not impair its effectiveness, and it is not necessary to remove the collar if a dog gets wet.

Avoid this collar and do your reaearch on any of them
If I could give this product zero stars, I would. We got a 16 week ( 4 month ) old puppy that had unexpected fleas, so bought this collar without reading any reviews, sadly with much regret. The puppy had it in over two days and will not eat or drink and is acting very ill. The pack says it was okay to use on at least 12 week old dogs. Please keep your dog safe and stay far away from this flea collar. I just found a note on an SPCA website that says that flea collars are toxic to humans and pets. They will not even see a dog if they are wearing one. That should tell us something.

DO NOT BUY AT ALL COSTS!!
I would give this brand no stars if I could. It is terrible! The company should not be allowed to produce or sell these collars. I wish I had looked up reviews prior to purchasing this. I put it on my dog but within days she had a terrible reaction from this. It cause some weird issue to her skin and even after removing it, I noticed that now she barely has energy to walk. She wet her self because she could barely stand up. Terrifying! DO NOT BUY AT ALL COSTS!!

DO NOT BUY
Has left my dog with very concerning symptoms and a red neck. Wish I had read the reviews sooner. There was also a lack of real instruction that came with the box. Whatever was written on the sides of the small box was it. Don’t recommend based on personal and shared experience at all. This product is harmful to dogs.

RAW RED SKIN
The reviews on this are horrifying. Forgot until looking at the reviews that this is the same brand that left my cat with a raw painful neck! Reformulate or SHUT THIS BRAND DOWN.

Do Not Buy!
Terrible product. My pup now has a wet, red angry neck. He is miserable. I should have read the reviews before I purchased. This should be taken off the shelves. I have purchased Hartz before with no issues, just wasn't available at Target.

DO NOT BUY!!!
I purchased two of these collars for my dogs to repel ticks and fleas. Five minutes after putting the collar on them, one of my dogs started scratching her skin aggressively, breathing weirdly, and experienced irritation around the eyes. My other dog also experienced the same type of irritation around her eyes. Had to give them multiple baths with warm/cold compressions around the eyes to relieve the discomfort. DON’T BUY THESE COLLARS AND RISK YOUR DOG’S WELLBEING. This product should be removed from shelves!!!!!

Terrible Flea Collar
My dog barely had this collar on for ten minutes before it started bothering his eyes. I had to flush his eyes and give him multiple baths to get the powder from the collar off of him. I will never buy this collar again and it should be taken off the shelf.

This doesn't work
I bought three of these for my three indoor dogs. These Treatment Collars do not protect, kill, or repel fleas. This product doesn't work, and I do not recommend it.
