So, the other day I was out the back hanging washing when I heard Luke blowing bubbles in his clamshell pool with his nose. I turned around and watched him for a bit to see what he was doing. He stood front legs in the water, back legs out, sniffing around with his muzzle underwater, blowing bubbles, pulling back out to clear his nose every now and again before going back under. He'd then pull his head out and chew on something before going back for more.
I couldn't think why he was doing this and then I remembered I had scattered (threw everywhere in a rush) some dry food around the yard earlier in the day and remember some had gone into the water. Luke was sticking his nose under, hunting out the pieces picking them out, eating them, then returning to find more.
Has anyone else's dog done this? I know dogs are good with their noses...but underwater? As far as I could tell, he wasn't finding them with his eyes as they were above the water.
