Merlin – our little schnauzer – loves vegetables and fruit. I use cucumber as his training treat, but he is also a huge fan of snap peas, apple and broccoli. Once, when he was a smaller puppy he was (accidentally) left alone with some braaied ribs and corn cobs. He chose the corn and left the ribs untouched.
Maybe I should not have been surprised when he took a big liking to strawberry. However, he gets it without the sugar.
