We have a very sweet 7 month old Beagle. My husband works from home and I do not work. There is someone at home 95% of the time and it seems to have created a separation anxiety problem on those times when he is left alone which has only become apparent with the warmer weather. With the weather being so hot we cannot take him with us everywhere.
He will whine and howl, and gets really destructive, he has destroyed all his beds, and most toys. We leave him with puzzle toys and things to keep him entertained but it doesn't seem to last long. He will also whine and howl if we leave the room and he cannot follow us.
I have only ever had 2 dogs together and not had this problem before, we are not sure that getting him a friend is the right thing to do (it feels lazy), but also not sure how to nip this in the bud rather than dragging it out years.
