I have a 2 year old Australian Shepherd who I show in confirmation shows. If it is late in the day and hot outside he has no energy in the ring. What can I give him to help this situation?

Ha ha, I used to have this issue with my male Sheltie. Wanna know what worked really good?

I had a female in heat. I wiped a piece of tissue on her vulva and kept it safe in a baggy far from my male until the show ring. Just before we stepped in, I let him sniff the tissue.

What boy wouldn't perk up to that scent?

Works great, isn't bad for his system and there are no rules against it.
