Thread: Male dog being pathetic over new bitch

I just acquired a lovely 1yo female working dog and our male dog is being really pathetic over her. Whining, chattering teeth and drooling over her. Hes unfixed and neither is she. She had her first heat 2 months ago.
I also have another bitch who is spayed, she isn’t so bad but was chattering her teeth for a while when following her.
Will the male pull his head in eventually? He’s older and it’s only been a few hours. I have never had an issue with female and male dogs behaving this way unless one is on heat.
