Cheers for the answer mate! Very happy to hear it's going well for you. Must take a lot out of you to get through such stressful situations - but hey, it's all the sweeter when you manage to beat the challenge!
I'm sure you'll be great at it as well - you seem to love dogs and I'm not sure you can get much better experience than the one you said you have. Glad to hear it's going so well!
Keep grinding and don't let up - that's where all the fun's at!
