Abby is 7 months as of yesterday and got her first heat cycle today. i dont think she nor trevor no what is going on. Trevor surprisingly hasnt tried anything yet but they wont be allowed to be together unsuprivised until this is over. I have a couple of questions tho...how long does an average corgi heat cycle last and howmany do they have a year? i am going to get her spayed before he second one i was just woundering.
