Just back from walking Fraser along the seawall and watching him at one point display the strangest behaviour. We were coming back along a bit we'd passed not 15 minutes before and suddenly he took great interest in some smell along the edge of the path. He's always sniffing, but sometimes he gets downright forensic about things. This time he was clearly tracking intently in that wide legged, waddling way when they are hot on the trail of something really, really interesting. What was different about this time was he was clearly spooked, his tail glued down, back hunched and showing every sign of being afraid. He was away in a world of his own and every one in a while as he was casting about, he'd throw his head up to look around him as though he was afraid something was about to pounce on him. He tracked along the path, circling, giving some spots extremely close attention and all the while, tail tucked and back rounded. This is an ordinary path along the edge of the sea with parking stalls on the other side of a low wall, completely open, cement and, as I say, we'd just come along the path about 15 minutes earlier and he was perfectly normal. Eventually I lured him onwards, but it took a while before his tail came back up to its usual cheerful position. I know cats seem to create fantasies for themselves, but do dogs do that? And he was really afraid. Thoughts? Anyone seen their own dogs ever behave like that?
