Thank you all for your kind welcomes.
Bravo does really hate rain, especially if it is last thing before lights out and we need him to go outside and be clean - considering building a covered area in our garden for him to use as a latrine!
eeeefarm - the cross is only what we were told by the rescue centre (Battersea Dogs Home in London, if you've heard of it). My boss at work has a pure GSD and Bravo shows some of the traits of her personality, but there are others that appear to be pure Basenji. For example he will avoid water (puddles, streams, the sea) at all costs, he will clean himself all over every evening and almost as soon as he is in a vehicle, even if there is the smallest amount of dust or dirt on him. He will pursue anything that moves, particularly squirrels, rabbits and even the odd goat (we have them where I work). He is a very lucky dog in that he comes to work with me everyday - I am a Park Ranger, so he has almost 1200 acres that I look after to roam around.
I will get a few more pictures up on the site soon so you can see him properly. He currently weighs about 18kg (40 lb US) and is pure muscle.
Think that's about all for now
