Thanks Doc, I'm very lucky to have my boy still with me. The timing of it all was crazy.
I regularly donate Plasma after work, which can take anywhere from 45mins, to an 1&1/2hrs. This same night they asked if they could take whole blood, which is over an done with in about 15mins, so I arrived home about 1/2hr before normal.
Tank was not waiting for me at the back door like normal, but Cooper was, which straight away was weird.
I called out to him a couple of times, and heard some noise coming from around the corner, and when he finally appeared he was staggering around like crazy but all he wanted to do was to get to me.
The vet agreed that it looked like a snake bite, so I immediately told him to give the Anti-venom. Luckily, down here in Tassie, we only have 4 snake breeds, 2 of which are venomous. Unlike the mainland, both snakes venom can be treated with the one anti-venom.
As you can see from the photos below, Tank has to be near me at all times. He nuzzles any chance he can get, and flops down on top of me if given half a chance.
Cooper is his own keeper most of the time, and prefers to try and keep a ball or tugging rope away from you at all times!
