Bulldog attacks lizard through glass door

Dozer the bulldog doesn't quite understand the concept of glass. In recent weeks Dozer "befriended" a lizard named Henry, who chills in the sun on the outside of the house.

"Dozer would just sit for hours watching him," his owner said. The beloved dog was a gift for surviving an allo stem cell transplant.

But after watching Henry for so long, Dozer "finally decided Henry had to go."

"Now everyday Dozer waits for Henry to come and either attacks him through the video or just watches him. It’s super funny," the owner wrote.
