Our dog Tippie just got her summer shave. We did it ourselves, so it doesn’t look great, but it does help to keep her cooler. Tippie is half German Shepherd, half Husky (a ‘Shepsky’ to us), and she has incredibly long, thick fur–which makes her very hot in the Texas summers. Her undercoat is very light, so when we shave her, she is a completely different color. We call her ‘beige dog.’
Before and after pictures:

P.S. In case you’re wondering, the red collar with the black box is her shock collar for the invisible fence. We have a wooden picket fence around the back yard, but Tippie tends to dig under it and/or chew her way through it, so we keep her from the wood fence with an invisible fence. She’s a special needs dog.
