Max was groomed at 5 months. I got him at 4months and the breeder I got him from had never bathed him! I had to get him clipped all the way to his skin just to get all the mats out. I felt so bad
Thankfully it was still summer months so he wasn't cold.
Now he just gets a face trim every 6 weeks or so until I want to trim more than an inch off the rest
