I am thinking of adding a second pooch to the family. It wouldn't be until next year so I've got bags of time to think but I want to start thinking seriously about it in advance.
I already have Bob, a nearly 6 yo greyhound. I will have another rescue dog. I'd like a smaller dog than a grey. I don't care about breed or sex but it needs to be a breed happy with two thirty minute walks on a quiet day and be up for 3 hours plus on a busy day.
My questions are, does it have an affect on the relationship with the first dog. Will he stop being 'mine' and bond with new dog more?
Is it much harder work, or like kids, do they slot in 
What breeds might fit with a grey? Or do I just find a rescue and let Bob pick his pal?
Basic questions I know but as I said, I have time, I'd love to hear your experiences.
