My girls are DH's babies. Mikki is his love! Rosie is a momma's girl. Believe it or not, a yorkie has a way of melting men's hearts. My dad is a construction worker. Years ago he had a Yorkie who was his baby! We used to think he loved her more than us!
After she passed away, he never got another yorkie. He still talks about her to this day! She totally melted his heart! As a matter of fact, he was thinking about taking Mikki if we didn't keep her.
So your DH is alright!!
He is showing you his real love for your yorkies!!
