My dog loves this ball
Color: Green
The battery on this lasts forever. The random on/off motion and when it gets touched inducing motion just keeps my dog guessing and occupied for a long time. My dog's tail is wagging the whole time.

Great ball
I have bought two of these in different colors. My Yorkie loves them. They’re very interactive even if you don’t put the cover on it they move and if he’s not playing with it, it tends to go into sleep mode.My Yorkie got the cover off the ball within the first two minutes. But he loves the ball. Now bought 2nd ball. The ones with covers don’t work he rips the covers off.

Super Fun
Color: Green
One of the most entertaining things you could buy. The dogs go crazy over it and have so much fun. It's a bit loud on hard floors, but honestly worth it for the laughs. Seems pretty durable too.
I have 2 labs; one started out uninterested and the other started off scared of it, but not too long after, they both started going crazy, tossing and carrying it around while it shook.

Great for dog who loves chewing small “tags” on stuffies
Size: Rabbit & Pig
My dog loves chewing the small tags or ears etc on plushies. He will pick one ear to chew on the little stuffed dogs from Petco, chew it until it’s starting to get shredded and I have to cut it off, then switch to the other.
I picked these toys specifically because they have SIX little tag-like parts that stick out, not just the two ears. He loves them! He is a 10 lb maltipoo and can easily grab and run with these. Loves the crinkle paper inside, loves the squeaker in the head, and LOVES the little parts that stick out for him to chew.
We just got them today so time will tell if they are durable, but they seem well constructed and he’s happy, so I’m happy.
Update: it’s been a week. I gave him one of the toys and he of course chose one ear to focus all his chewing on. That ear has been chewed and chewed and it is just getting to the point it’ll need to be trimmed off soon due to raggedness. Then he’ll still have five little nubs left on this toy to chew. So it should take him at least 6 weeks to chew all of them. By comparison, when we get cheap stuffies on Amazon, usually both ears are totally finished within a week or ten days. This is definitely more durable and worth the money!
