Piper is 5.5 months and she loves to suck on this pillow chum that came home from the breeder with her. The breeder sent a bunch of toys home, and I found that she likes stuffy animals that have long dangling legs, squeakers, and, curiously, anything with ears. We joke she is taking out her frustration of having her ears posted on the poor little stuffy's ears that she insists on trying to chew off until we take them away.
My son picked out this snake type thing from petco that takes a beating and is definitely one that she has loved from day one. I just googled it and I think it might be the Invincible Snake Toy for Dogs. There were two lengths and we got the shorter one, which has worked great. Once she got a little older the Kong Wubba came home and that is right up there with the snake. Both those two don't have stuffing and are durable enough that I can leave out for her, with regular inspections for wear of course. The Wubba might be too big at first, it has this heavy rope ball on it. It is great because it is made of tough fabric, has dangling things to chomp on, has heft to throw well, and squeaks. She know's those two toys by name. A good old rope knot that was a $3 add-on item on Amazon and a similar one that has a tennis ball on it from Petco round out the favorites.
Oh and the "stuffed" animals that you put water bottles in (via Velcro closure at the bottom), as well as these no stuffing animals that have sheets of crinkly plastic in them instead were a hit when she was little. The latter ones she is kind of hard on and don't keep her interest any more.
She isn't a super chewer like other dogs I've had, but on the chewing end she is a fan of the Whimzee sticks (size large, at least once she was really chewing, and the tooth brush ones are shaped such that she mows through them in one sitting, which I don't want to pay for). The smart bones she really liked (looks like a rawhide with knots on the end but is made of digestible stuff), but they contain corn, so I decided against them after the first bag. The puppy nylabone saw some action, but not enough that I felt the need to rush out and get the sturdier ones later. She goes nuts for RAW (cooked can be dangerous) beef bones you get for bone broth. With a kid and carpets she only gets it out on the porch or in her crate with the bed removed, so it doesn't come out of the freezer as often, and then only for as long as she is gnawing on it (then back in the bag in the freezer it goes). Hard plastic juice jugs with a narrow neck and labels, caps, and that little ring below the cap removed are great (put some kibble in for an easy puzzle). Same goes for water bottles, but I keep a SUPER close eye on her with those. I would skip them all together if they weren't her favorite thing ever. When I can't keep as close an eye I use the one in a stuffy cover as mentioned earlier and leave the lid on the bottle to trap air so it crinkles longer. She prefers it without the cover the best.
And on the puzzle end the PetSafe Busy Buddy Magic Mushroom is great, but while it seems super sturdy and I've heard great reviews on its durability, it makes me whince when she wants to just decides she wants to sit and gnaw on it. I got it after reading this article I found (is full of great ideas): Pitlandia: Top 10 Food Dispensing Dog Toys
She loves the original Kong only as long as it is stuffed, then she couldn't care less.
Ok, reading this I think I spoil my dog
Good luck and enjoy your puppy!
