PORT ST. LUCIE, Fla. — The special guest at Mets spring training on Tuesday: Bear, a 13-month-old black Labrador retriever from K9s For Warriors who is named after “Polar Bear” Pete Alonso.

Alonso and his charity, The Alonso Foundation, are sponsoring Bear’s special training to become a service dog for a veteran in need. K9s For Warriors provides highly trained service dogs to veterans suffering from mental health issues.

Bear seemed to thoroughly enjoy being on the field and in the dugout — and all the attention that came with it — during the Mets’ workout. He took a liking to Alonso’s blue and orange batting gloves, turning them into a chew toy. Alonso let him keep them.

Bear is separate from but similar to Shea, a yellow Lab and a fellow service-dog-in-training sponsored by the Amazin' Mets Foundation in a partnership with America's Vet Dogs. Shea frequently appears at Citi Field and other Mets events.
