Best frisbees I’ve found for an active dog
Pattern Name: Assorted, Size: 9" Pack of 5, Pattern Name: Assorted, Size: 9" Pack of 5
My dog is an ACD/Border Collie mix, so he is absolutely obsessed with anything that flies or moves fast. We’ve gone through a lot of frisbees over the years, and these are the ones I keep coming back to. They fly really well once you get used to them, and they’re soft enough that I don’t worry about his teeth or mouth the way I do with harder plastic discs. They also hold up surprisingly well considering how rough he is with toys. Mine get used constantly in the yard, at parks, and near the water, and they’ve lasted much longer than most dog frisbees I’ve tried. I’ve bought several packs over the years, but honestly most of the damage has happened because my dog likes to lay down and chew on them after playing fetch. If I leave one sitting on the ground too long, he’ll eventually destroy it. That’s not really the toy’s fault though. In some ways I actually like that they’re soft and flexible enough for him to comfortably carry around and chew on a little. Another thing I appreciate is that they’re washable. After a muddy or slobbery session I can just rinse them off and they’re good to go again. For an active dog that loves chase and fetch games, these have been excellent.

Very durable
Pattern Name: Assorted, Size: Pack of 2
Awesome frisbee. Even if you don't have a dog! It's actually just nice to play with as people! Flies great. Left alone a dog with l can destroy it. It's not a chew toy, but it is a great game of fetch. Perfect size for medium and large dogs, plenty durable.

Very durable and amazingly fun
Pattern Name: Assorted, Size: Pack of 2
My dog loves frisbees, but now this is the only one I’ll ever buy again! If you’ve ever had a dog frisbees you know that some dogs can eat/chew-up a frisbee in literally minutes. Not this one, no way! I’ve bought several of these because I keep one in my truck, one on my boat, one for the backyard, and one just for the dog-park (can you say “community drool”? I take these everywhere (see videos) and every single dog that gets ahold of it loves it. As a matter of fact the only problem I’ve ever had with it is when I take my dog to the dog park all the other dogs fight over this frisbee. As far as quality it’s tough as nails, sure if my dog sat and gnawed on it for hours he might eventually tear it up but it would take a very long time and I would see him chewing it up. My dog and all the other dogs at the dog park will gnaw and chew on it and not one dog (from labs to retrievers to pitbulls to Rottweilers to even a malinois, a German Shepard and a massive cane corso to a little cur of a dog) not one has torn it up, and they ALL play tug of war with it. It’s great for teaching young and old dogs how to catch because it is soft enough not to bounce out of their mouth and they can catch it with a good grip. The best thing ever: it’s malleable and can be easily put back into a round shape even after heavy pulling. It floats on the water perfectly and will not sink no matter how wet with water (or drool!). On top of that it’s very light yet is easy to throw in even heavy wind, and as a frisbee guy for decades when I say it throws good, it’s pretty darn accurate whether wet or dry. Personally I have found I like the pink one the best (not the pink swirly one, even though it’s fine I like the black edging on the others as they seem tougher and more solid for throwing). The solid pink ones are easier to see in water, grass, dirt, etc. I have bought 5 of these so far, not because they get trashed or fall apart, but like I said it’s because I have one for every purpose. Highly recommend the solid pink as best color wise.

Great frisbee for our golden doodle
Pattern Name: Assorted, Size: 9" Pack of 5
Love the product. Our golden doodle can chase these all day long. They are light enough and easy on him to catch them and they fly well. Only complaint is I wish they were a little cheaper. He does go through them

Amazing frisbees for dogs!
Pattern Name: Assorted, Size: Pack of 2
These are the best frisbees for dogs. They hold up well but do fade over time if left in the sun. Our border collie mix is an avid frisbee guy and these are his favorite. The float in water well and last for quite a while. He’s not a chewer so I can’t speak to the durability with chewing. I buy a couple every year when his old ones get faded and gross, otherwise we would continue to use these for over a year!
