Squishy and comfy
Very well made bed. Had I known about Amazon Basics brand sooner, I would have gotten two of these earlier. The other bed I purchased was a Snoozer XL and it arrived in a super compact state; the filler was even compressed and is therefore not as squishy and comfy as this Amazon Basics bed. The dog pictured is about 41 lbs, so it's perfect for her size (my other dog is a 70 lb pittie and he also fits on the bed).The 'hood' does detach, whereas the Snoozer one is permanently attached. Having the hood detach for washing the cover was another plus for this bed. The zippers are heavy duty and the 'sheepskin' is soft (I haven't washed the cover yet, so I don't know if it will pill). This bed arrived ready to use out of the box (very basic packaging); the filler was not compressed, so the bed is definitely more fluffy. This is the XL size and it is smaller than the Snoozer XL size but fits the corner of my room better. This is definitely worth the money.

I regret my purchase
Color: Blue, Size: Medium (Pack of 1)
A few things: 1) this bed is much smaller than you think. Even if you measure it the way it’s constructed makes the area under the flap super small. 2) my dogs, burrow under blankets, covers, everything. But they don’t burrow under this. It’s designed to be appealing to humans, but dogs don’t care for it. 3) you probably already read this another reviews, but the flap doesn’t really stay up at all. That wouldn’t be a problem for my dogs, but it may be for yours. My recommendation – don’t buy this. It’s a gimmick. They make others with larger areas under the flap that are more expensive, but it’s worth the money instead of wasting it on this.

My high energy dogs favorite puzzle!
Bought this to keep my high energy dog busy. He has many puzzles but this one seems to be his favorite, a lot of them he wasn’t very interested in and would get bored and give up quickly. This will keep him entertained for about 10-15 minutes and is a fun thing for him to do as an apartment dog that needs enrichment in the middle of the day! Love how cute it is, especially during football season, we will give this to him while we watch a game so that he can enjoy the game with us lol

Great toy for dogs or cats
Color: Clemson Tigers, Size: Large, Color: Clemson Tigers, Size: Large
Both my dog and cat love this treat finding toy. Dog (husky) can work it very quickly- the doors slide a bit too easily for him but the cat also successfully hunts up his treats as well. The quality seems nice and despite their use, still looks brand new.

Fair product
Color: Ohio State Buckeyes, Size: Standard
Product works great and looks nice. Stickers come up easily. Maybe not worth the price. But still is a good product.
