Some have a 'play drive', some have a 'food drive' and some have both.

My RR/Lab has never had a play drive. No matter what kind of toy I bought him, he just ignored it. However I was able to teach him to retrieve.

I would put a soft toy in his mouth, then take it away, then give him a little treat. It didn't take long for him to learn if he gave me the toy he would get something he wanted.

For the past 10 years now I can toss most any toy and he will retrieve... in hopes of getting a treat.
