Cleon

Their short legs don't suggest they'd be much good at jumping - their leg proportions don't look much longer than a dachshund - so I'd say cut it.
They're about a third the weight of the SRD Dog, suggesting -2 Str.
Personally, I'd make it -4 Str and -2 to Dex, since the SRD Dog is over-statted and the original Bushdog had 1/4 Hit Dice.
Make the Bushdog a half-HD creature like a cat, which is a similar size?
HD 1/2, Str 9, Dex 15, Con 15, Int 2, Wis 12, Cha 6 ?
