Hi!
I have a 10months old SBT and hes pretty good all round! Mostly well-behaved and obedient and very friendly!
He's not particularly destructive although if he gets his jaws on sth tasty..

Seriously normally I am the one to leave him alone at home (as I leave later than my partner) and hes mostly well-behaved during that time. He had a few "accidents" (spoiling but also chewing on the wooden boards) at the beginning but now hes mostly good! I take him for an hour walk/run in the morning and usually same in the afternoong, and some more during the week-end and we try to exercise him "mentally" as well (with "find-games", "dog-puzzles" etc)!
Anyway the point is; when my partner leaves him alone (rarely) he will LOOK FOR sth naughty to do..for example, if there is a bag of some sort on the dining table, its been there for weeks and he didnt care, but the day my partner leaves him alone he will grab the bag (god knows how! Hes grown up without my realising i suppose!) and try to destroy it..and everything else he can lay his paws on..he even had a pretty bad go at the wall once..I left to go to India for 2 weeks and my partner was alone with him...well the house wasnt in a pretty state when i returned (oki, not that bad but still!! far from what he would normally do!!)
AND its the SAME problem with a dog-sitter we have; basically we have a couple who comes over when we need Diego taken care of (when we have to leave him alone more than 6hours say - it used to be once a weeks roughly, now it is less frequent), and mostly they come together or just the girl...but the days the guy only comes Diego does exactly like when its my partner!! Chews on everything etc etc (we usually leave him with a chew bone but he normally waits for me to be home before he starts on it..dunno why..but on those occasions the chew bone has usually disappeared by the time im home!)!
So I dont know what to think really..
Why the need to chew/destroy when he is left alone by my partner or the male sitter and not when its me or the girl??
Both guys are very good with Diego so I dont think its a dominant/anxious type of problem...
Is it sth to do with the fact that they are men and hes a male too? How?
Or is it because he is normally left alone by either me or the girl and he is not used to being left alone by the boys..?
What to do??
Any suggestion welcome
Cheers
Isa - a really puzzled owner!
