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.

This is my dog Dozer he was a gift for surviving an allo stem cell transplant, I have cancer and he’s my buddy. Everyday this lizard who we call Henry hangs out on the glass door. Dozer would just sit for hours watching him. April 15th 2018 is the day he finally decided Henry had to go! In the background is my 5year old son and me we were laughing so hard. So now everyday Dozer waits for Henry to come and either attacks him through the video or just watches him. It’s super funny
