Thanks for ending my work day with a chuckle.
I have never seen TJ 'hump' a toy - thank goodness...BUT...he has tried to hump Roxy - way back when - and also after he was neutered.
And just last night, TJ just kept sniffing Roxy's privates. She was getting annoyed and would sit so he could sniff her anymore. Then they started to play chase and wrestle and then TJ jumped on her and started to do a little humping. Me and hubby just started to laugh and TJ quickly jumped off of Roxy and ran up the ramp onto the couch and jumped on me and was giving me kisses
I think this is a dominance issue
