Looks like it’s all going well.Terriers have their difficult reputation but in the right pack they just fit straight in.
I hear so many bad stories about ( in my case)schnauzers being aggressive,yappy dogs...my girl was refused by all the puppy buyers who came to see the litter..she was declared to be the most difficult,growling dervish of the pack...yet with a bigger sweet dog ( my sweet st poodle)she fitted straight in.
Im so looking forward to see the pack walks with your gang...little Colin will be in his element.
