I have a cockapoo who is 4 months now and for the last two weeks I have noticed anytime he runs or jumps off of something his leg makes a clicking sound, he is very, very active and his leg doesn't seem to bother him at all. I just don't know what could be the cause of this. I guess I might be overreacting since I just had my beagle die not to long ago . Just was wondering if anyone elses dog legs do this ? TIA
