She looks beautiful ITG!
We had a GR for 14 years and when she started getting hot spots near her bum/tail, it was recommended that we groom her down. It was very drastic but in all the years and summer months, she was much more comfortable. By October, all her feathers came back and her coat was beautiful.
To her 13th year, we had her groomed where she looked like a Yellow Lab and the hot spots never returned. She also felt young and spunky after every groom!!
and own personal experience.
She sure does look beautiful and hope everything works out with the results.
