Most any dog can be trained to hunt turkeys as long as they have an interest. Get some wings and tails as play things but only use these while you are with her while letting her know you are very happy when she shows interest.
If you are not hunting in steep hills or mountains the short legs should be OK. Boykins are very small dogs with short legs and a lot of guys use them for turkey hunting with great success.
If want, email me the full picture and I'll resize it and send it back to you. firstname.lastname@example.org
congratulations on your new hunting partner, that is, if, your wife will let you take her.
