undercoat

Currently, I own 4 shelties. I want to keep them cool and comfortable in the summer. I am not very good at getting all their undercoat out, so I would like to get them professionally groomed. I can't do this more than once a year. My question is: When would be the best time of year to bring them...

Hi, When you brush your sheltie you have a lot of fur coming out!! Take advantage of that and keep it to have a keepsake made out of it. Trimmings could work to if they are long enough.
