Awesome it will make him feel better anyway then knotted dirty hair..( often I shave my furbabie)as a woman with hair n hate knot's, heat n dry brittle rats nest hair as I refer to it shaving would be my thing if I wasn't afraid of being rudely talked to or about because of it! Just remember sun little by little till his skin gets more accustomed to actually hitting skin vs hair? Summers here in Texas are hot as hell I'm sure your pup will appreciate it as long as he doesn't get sun burned? winter I put a onesie on mine so hair isn't ever needed..lol. but mines eight lbs?
