HELP! Male Basset with no interest to Female in heat

I am new to this forum, but I have a question. We have a basset that is 2 years old, her name is Puddles. We are using a Male who is 5 years old to breed with. Rufus, the male is not interested in Puddles, he will sniff her for a second then turn or walk away, or she will wag her tail and wack him in the face. Either way he is not interested and just keeps walking away. Is it possible that he can't smell her, that his nose can't smell?? He is definitely not neutered, so I don't know what is going on. This is both Puddles and Rufus' first time, is it possible they don't know what to do, but shouldn't he show more interest??
Thanks in advance for advice
Kristi
