We were reading about what human food dogs can eat when we saw that pineapples were on the approved list. Someone wrote that frozen pineapple makes a great refreshing treat during the summer and their dog loves it. Since B is a big pineapple-eater during the summer months as well, we decided to freeze a couple of pieces for Regis. He was a little unsure with the first two bites and dropped some bits on the floor, but by the third piece he was enjoying it whole.
