Works but fibers are an issue
Size: 10 Pacck, Color: Multicolor
These were great for my small Yorkie puppy. She had to is bite issue and we needed these tennis balls to help her stretch and correct her jaw. Squeaker works well. The chewing helped but it wasn’t necessarily “chew resistant”. the little fibers from the ball will start to come off and dog will hack a bit. For that reason, I am unsure of the safety of it long term. Must be supervised always. Will try a def brand next time but this helped our lady w her jaw pain/issue.

I thought id see how my Boston wud react with so many balls to choose from LOL! I love that the squeaker is internal on this toy. On the ones that hv the plug style squeaker my Boston will pull it out then proceeds to pull off the material and a slimy ball is no fun...LOL

good for puppys young dogs, handle is separate, locking carabiners on both ends
Color: Orange, Size: 30FT
This is a good sturdy leash but probably wouldn't stand up to a conscientious chewer if your dogo has that bad habit. I like this one because the handle is separate so it can be used both as a tie out lead and as a regular lead. I also like the "locking" carabiners that should not open accidentally. I bought the thirty foot version because my new puppy loves to go outside then refuse to come back in or let me catch him when I need him to come inside (not catching me silly Hooman). When he's bigger I won't be so concerned about him being outside alone but since I'm in a sort of rural area, we have the occasional fox and hawk around when the sun goes down. Not too much to worry about in the way of pests but every puppy parent has an obligation to protect their young'un till they gain some wisdom. I have stairs in the back of the house, the way this is made I can attach it to the banister easily so I don't even need one of those tie stakes that bury in the ground. The price wasn't bad, the hardware looks sturdy and should last awhile. I just also bought the fifteen foot version, same quality as the thirty foot product I like that the handle is separate so it can be used as a tie down or a leash easily. My only big wish would perhaps be some more color choices, the orange is nice for visibility a yellow would be nice and then maybe some other colors like red/purple would be good as well. The thickness of the rope means that it doesn't "easily" get tangled into a giant knot. I leave the back door open and puppers can go in and out as he likes but he also sometimes runs around in the living room and thus far haven't had any large tangles to unwrap. He did manage to get the leash caught around a piece of tree branch that was on the ground (and complained loudly) but that was only because the branch was too heavy for him to drag the lead off of by himself. These leads are worth the money, I will likely buy a couple more to keep in the vehicle and other locations besides home.
