Great Toy Bundle
Color: 9 Pack (No-stuffed Fox)
My puppy loves these so much that I purchased a second set! The toys keep him engaged, are very cute and soft, and so far have withstood the wrath of a slightly psychotic furchild! Highly recommend!

My puppy loves this set
Color: 9 Pack (No-stuffed Fox)
It’s been 15 years since I had a puppy so after I adopted a 9 week old puppy, then I realized I had no toys for her! I wanted a variety at a reasonable price. And fast too! This arrived the next day and she immediately started playing with everything. I think her favorite is the fox but she loves them all. The first time she heard the avocado squeak was priceless. She also loves the rope toys but they shred so I limit her time alone with them. These probably won’t last a long time but they were a good price for a lot of variety of items. She is happy so I’m happy. Thanks

Poop bag and treat dispenser questionable
Color: 9 Pack (No-stuffed Fox)
This is a hard one. The toys seem great. The whole box smells of the poop bags and I don't think they should be a part of the purchase. The bigger issue i see is the treat ball seems to have a weird plastic coating on it. Almost like a thin clear coat that gives is a peeling feeling and I don't think it is safe for the puppy. Excited to see how she likes the other toys though.

Wash first
Color: 25 Pack (Value-Toys)
These are excellent and very well made for a 1 and 1/2 lb Chihuahua girl. I don't know how much they would hold up for a bigger dog but they're perfect for a little one. We always wash all of her toys first and I didn't notice that there were garbage bags in there. Which ended up being a good thing because they were scented. Washing help to get most of the scent off and it took the scent off of the toys. She hates the scent. Me too. It was nice to have the doggy bags though and we would prefer them not scented. We didn't dry the toys and we let them air dry which is a good thing cuz it might have ruin the bags. The bags are a little small and short compared to the normal bags that you buy but overall this is a really good value and she loves all of the teethers and ropes very much. Very well made. Nothing has fallen apart and she has chewed it a lot. I don't know how it would be for a bigger dog but for one and a half pound puppy Chihuahua it's perfect
