i am house sitting a sow, she is a year old and double the size of my boar whos 4 months old. they get along well if they are only together for a short time. If they are together too long the sow pulls rank and snaps at him. So with this all i separated tem but she chews at the gate and pulls at it and he whines for her. I dont know what to do, they fight whan there together but whine for each other when apart. The sow got sprayed so theres not chnace of pregnacy but hes still a little horn dog and i thinkt hats what is bothering her, or piggie pms! any sudgestings welcomed!
