Is it okay to use large dog collar on small dogs with bigger necks? Or can you use the cat collar??

You have to use zip ties or pipe cleaners on a normal leash collar to attach a partial collar. There is no difference chemically between a cat, small dog, or large dog seresto collar. The only difference is the length and on the large dog it is also wider. In fact, when seresto first came out, the product only came in large dog and a small dog/cat combo collar. Seeing that they could make more money marketing a small dog AND a cat collar, they made the 3 products. If you look at all the data on them, they are the same.

Is this collar water proof for dogs who swim everyday?

I wouldnt trust it for a dog that swims daily. But as far as the people who said it didnt work because they happened to see some fleas or ticks around the collar...you know the collar cant INSTANTLY kill fleas and ticks...like it takes a few hours at least so if your dog goes outside and picks up new critters, its entirely possible for that to happen multiple times and for the collar to be working perfectly. Once my roommate and I (her 3 cats and my 2 small dogs) had all our pets treated with topical stuff but we got a flea outbreak anyway that last MONTHS and we used everything out there including all natural stuff to spray our house down with and NOTHING WORKED. Finally I bought the seresto collar for 1 of my dogs and FINALLY the fleas were gone! from just ONE of the animals wearing this collar after 8 other things didnt work. The vet said that it really depends on where you live and what year it is (like which products the critters have become immune to in that area at that certain time) for what might work for you. SO to sum up, just cuz you see new fleas or ticks on your pet doesnt necessarily mean anything if your pet went outside and picked up new bugs the collar hasnt had a chance to kill yet, also something that worked for someone else in their area at the time at worked for them may not work in your area during the time you use it. Frontline used to work great in our area of NJ which is tick country, but after a while it stopped working all together and the vets started telling people to switch to other things but many people still thought frontline was the best because they didnt know. Now, its not frontlines fault that critters became immune to it, it used to work very well. You just have to keep up with what is working in your area at the time. Ive been using seresto collars for about 6 yrs with no issues but then again, I had my dogs for 11 yrs on whatever topical flea meds I could afford without ever getting fleas or ticks until I moved in with my friend who had cats so maybe my dogs just arent prone to getting fleas. I rarely let them around other animals thy dont live with and I always walk them on the sidewalk, never near the woods. So who knows? And I certainly dont ever let the collars get soaked more than once during their 8 month wear.

How long is the small collar

The small collar is 13.25 inches long and will adjust down as far as needed. Once placed on your dog, you can cut off any excess (leaving about 1 inch extra on collar).
