Must Read before Purchasing!!!! Height is lost if you use this base!!!!
Size: 100LBS
I was so very excited about this for our umbrella - and then I put it together. I called my adult son to come and take a look - I had to be doing something wrong. To our dismay, I was not. The lowest pole in the umbrella system has 4 welded pieces with holes meant to connect to the legs, thus stabilizing the structure. The lowest pole measures (guestimate) 3 feet. When you choose this system, you do not use the original cross-bars, nor the original lowest pole with the 4 welded pieces. Rather, you use a newly provided lowest piece roughly measuring a foot. In doing so, the structure loses a total of almost 2 feet. For average-height individuals, this would not be a problem. For individuals 6' or greater, this is quite a problem. My son is 6'6. My husband is 6'2. I really wanted the portability of the product. However, we will be returning it for the kind that rest on the cross-bars. I wish someone had mentioned this in the reviews I read and saved me the trouble.

Bully proof?!
Size: 5 in
We have the cutest little pit/lab mix who destroys stuffed toys in about two seconds flat. It’s always a HUNT to find toys he won’t instantly shred. This brand has some of the best! They were in FiveBelow for a while and it was the only brand that stood up to him initially. He finally got through the first only after MONTHS so we bought a few back ups and they’re still going strong months later! They’re also not super heavy so these end up being the toys we play fetch with most often! 100% will be buying more in this line in the future!

Great Option

When this chew arrived, it immediately became a favorite. It seems sturdy and is soft enough to be dental friendly.

My dogs finally chewed pieces off of these bones but it took forever for them to do it and they didn’t chew very much off! These are great and I will buy more!
