So I have a 6 month old border collie and keen to “socialise” her a bit I took her to a socialisation class. It seems fairly well run. It is for age 6-9 months and we do practise loose lead walking etc then at the end they play together. As my dog is on the timid side I can’t decide if I am overwhelming her and doing more harm than good. 4 dogs there but could be up to 6. Two labs who were larger and older than her and one spaniel. She is more comfortable with spaniels as she finds labs a bit intimidating I think just due to their size. During the free play she joined in, ran around, came back and hid between my legs a few times when she wasn’t sure. Hide under bench a few times but came back out to play and she licked the other dogs faces a lot also did a lot of lying down and submissively showing tummy. She looked relatively comfortable and like she was enjoying it, but quite hyper stimulated by it all. I am just concerned that if I end up scaring her I could actually cause problems where there currently aren’t any. Can anyone advise?
