Oh Joller, you cant walk her while in season, not even in your front yard, every male for 10 miles around will escape and follow you or her scent right to your front door, you will have a dozen males camping in your front yard for a week or 2, all crazy to get at her.
Im not sure you realize how desperate they are to mate, and what they will do to achieve that.
My little fellow, dosent eat and goes totaly crazy when my girl is in season, so I usually have to send him to visit my daughter for a while, as they can really hurt themselves.
He had the male pill so will be ok now till it wears off, but i still seperate them anyway as he can still do the job, but just shoots blanks and is much calmer.
She will need to stay inside or out for a wee with YOU WATCHING her.
