I've talked with people about this before and still don't have it settled in my mind. I know dogs are pack animals and have been raised around other, their siblings, Mom and Dad, etc. I also know most will settle down into homes when they get 8-12 weeks old and do well but what if that particular one is older-say 1-3 years old and has always been around others of his/her kind and now is living alone with his Dad. In my case I live alone and there's just me and Bubba. Many times I think he "looks" like he misses being around the others he left behind, judging from a recent visit to see his breeder and being around old buddies he once had.
When I say he "looks" like he misses them I mean he looks like he mopes and has no interest in much and at times won't even chew on his favorite chew item-the C.E.T. Dental chews. He'll lick it a little and then put his head back down or he won't show any interest in his teddies he plays with. Many times he'll retire to his crate during the day until I call him out or hke'll come out on his own after awhile. I'll take him out to PetsMart or other such places and he really don't act friendly to the other dogs but just turns his back on them mostly. He's never aggressive just coy or stoic about others. When we went to see his breeder he was around his own kind and was an entirely different boy there, smiling and loving up to several, especially his ol' buddy Sonny.
Maybe I'm trying to make more out of this than there is using human psychology as I know zilch about dog psychology but try to read his body language and at times he just looks miserable even though he has the best any Corgi could want. It's just puzzling to me and I don't know if another companion Corgi would perk him up or not.Perhapas he's just a loner most of the time and this is just him...just fishing for opinions.
