for wee paddy.
I do think every dog handles it differently, some bounce back where others are justifiably in my opinion, grieving. My reason ing for getting a third was my fear of this.....I had it happen before and know my younger dog would be lost.
I think sometimes we underestimate how much of a bond they can have with each other.
Do you have any extra-special to Paddy walking buddies who you could meet up with? Do you have special walks, maybe a bit further away that are normally a treat, that you could take him ( sorry them both) to to bring out his happier side again?
Are there any toys that have really excited him in the past.......do you have a personal teddy that he isn't normally allowed that you could let him have, with mine the excitement of that would be a good temporary distraction.
It will get better, he will need time to adjust, like us
