ABSOLUTELY possible .... example;
My female pup is not in heat yet ... but she must be starting as my male started paying special attention to her ...."chasing" if you will ... I can call him off her now ...but when she is READY ... FORGET IT. BTW, she wont be ready for about another 3 weeks .. she hasn't even started spotting yet ..
Whitetails aren't in "The Chase Phase" yet ..... but they are still testing the waters if you will ... look at all the deer kills poppin up now ....
