Timid, Shy, Reserved Male Blue Merle
Hello everyone let me start off by saying I have a male blue merle that has come from a good breeder registered CKC and ASCA and I have had him since 12 weeks. We have socialized him everywhere and with everyone he loves our kids and all other kids. He is still shy, timid or reserved whatever you want to say. Currently enrolled in obedience and is head of class but does not like all people to pet on head and of course I tell them under the chin he at times in a situation of too much pressure will back up. Will this dog ever come around totally and should I have to worry about him fear biting even though we socialize him everyday? Personally I believe he never got a whole lot of socialization early before I got him but his litter mates were fine very social so maybe it is just him? He also barks at everyone that walks by the fence including other dogs but I imagine this is normal natural protective instinct?
Thanks for the responses in advance.
