Being afloat for just 2 months, can honestly say our 3 year old gsd dog has settled very well. His separation anxiety appears to have become less of a problem, now we've managed to train him to sit on a box on the well deck when we go through locks, or casting off and mooring. If he comes off his box, he gets told to get back up. He's happiest when knows what's expected of him. Plus he's less of a liability when he's under control.
Had to laugh at him this afternoon, he wanted to turn around, so he backed up along half the boat to turn around! They are just so bendy, and articulated!
Although he can swim, he always has a harness/lifejacket on as he can't get out of the canal without help. Daft dog's fell in 3 times now! Last time was in the pound at Atherton top lock.
I won't let him swim in the canal (apart from accidents) as there's so many things he could pick up from the water.
So far touch wood, there's been no need for a vet, though he did cut a pad so we kept the area clean ourselves.
