Best Flea Collar to Buy in 2020: Safest, Lasting, Good for Puppies & More

It’s thought that every one out of seven dogs has fleas, which means it is a rather big problem.

Fleas aren’t just a mere annoyance. They are painful, and they can predispose your dog to numerous health conditions. That’s why it is best to get rid of them when you can, or even better, prevent them before they even show up.

Prevention is relatively easy and can be cheaper than actually treating a flea infestation. By finding the best flea collar that works for your pup, you can get flea protection for months before it needs to be replaced. 

If you’re asking, “what is the best flea collar for dogs?” and don’t have time to read through this whole guide, I’d say flea and tick collar from Craveit is a good choice. It’ll last up to 8 months before it needs to be replaced, and it’s very affordable. The waterproof design means you don’t need to worry about it getting wet. There’s no reason to leave your dog unprotected when this is an option that seems to be working for many dog parents. 

But if you want to stick around, read on. I spend 11 hours working on my research for this article, so you don’t have to.

Most popular flea collars: Salvo vs. Seresto

Salvo and Seresto are the two biggest name brands when it comes to flea and tick collars. It’s hard to go wrong with either of them, but there are few differences in their products. 

Considering that it’s a two-pack, the price for Salvo flea collars is rather good. Each one will last 6 months, but together, that’s a year of protection for your dog. It uses natural oils on your dog’s skin to keep pests away, and it can withstand water to stay effective. The specially designed triple clasp means that it’ll fit on your dog comfortably and securely. Some users complain that the collar is flimsy, and it may break.
