This is my 7 month old toy chihuahua name Papi Chulo...well, he's really my wife's dog. He still does not lift his leg. He will squat to pee and do alright for a second, and then he begins to arch his back resulting in the pee hitting his chest and just rolling off of him. It really is disgusting. After every time he pees we have to wipe him off. He's a really cute guy. Other than still being a chewing machine, he's well mannered...I just wish he would lift his leg! Any suggestions or is this just a natural progression that may never happen?
