My pal

This is my 9 year old cross border collie/springer spaniel boy charlie, he has one of the strongest personalities i seen in a dog very playful and just been diagnosed with arthritus bless him so not as active as he used to be, still has excellent senses, all the people he has instantly taken a disliking to turned out to be weirdos (not the good kind) and theres many times hes made us laugh, understands every word i say but doesnt really listen to any of it, can he be any more like my bro
