He is a very lovely, playful dog,doesn't matter to put him with other dogs...however,maybe he get hurt by human so he is quite scare of human,but im not worry about that because i think he just need more time to get mental recover...from the 1st day to now i saw his big change,at the beginning no people can go nearby, now you can touch him, and walk nicely with him. he has good temper even nail cutting, he wont show u his temper and u give command "inside", he will quickly run into his kennel without complaining. i want to find someone that can spend time n money on him...tin food n salmon flavor dog food are his favourite.
