I bought 2 bottles for my German Shepherd's 1-year birthday. He took 2 hesitant sips and that's it. I gave one bottle to my neighbor's dogs (different breed & age), they wouldn't drink it either. I like the idea, but they didn't care for the taste.
I'm a volunteer for a local animal shelter and I recently made up several large gift baskets to use as prizes in our Tricky Tray Fundraiser. I used the Bowser Beer in three of them - an Octoberfest Basket, a Beach Basket, and a Baseball basket. Everyone commented on the unique product and it was a big hit with the bidders. I saved one bottle for my own dog, and he truly enjoyed it.
