Sammy

We once had a dog who could only be described as a ‘dumb blond’. Sammy was ¾ Golden Retriever and ¼ Red Setter (a breed not exactly known for it’s intelligence). No matter how much we tried, Sammy could not (or would not) learn even the most basic commands. It was impossible to get him to walk quietly on the lead; he insisted on nearly choking himself every time. He had a great liking for squeaky dog toys, to the extent that, rather than barking, he would bite down on the toy, causing it to emit it's high-pitched squeak. This unfortunately (and unsurprisingly) did not have the desired effect of scaring anyone away. In fact, he even had trouble chasing cats away. Most of the time they would not run from him unless he had another dog with him to help him. This did not discourage him, and he continued to try and chase cats, often skidding to a stop in front of the immovable felines.
Well, who ever said intelligence was a requirement for being man’s best friend?
