Hi, my name's mike and I'm from Melb. Firstly I'd just like to say that this is a great site with some great info which always helps!
I'm a first time dog owner and I have a 7 month old pure preed Rhodesian Ridgeback (picked him up when he was 8 weeks old). He's very stubborn and can be cheeky at times, but all in all he is a very well behaved puppy (he does have his moments though! haha). He's only 7 months however on his last visit to the vet he weighed in at 40.5kg, so my guess is he is going to be a big boy as he still has a fair bit of skin to grow into!
I'm sure I'll have a few questions, but for now here are some pics
