I have a three foot wide sliding glass door along with its three foot wide still window wall that is attached to its same six foot wide frame in the back of the block/brick house. During the feeding time, my dogs keep pushing the door toward to the family room. I am afraid the door may be knocked down and the glass breaks. So, I would like to replace them with a single three foot wide wood door along with a heavy duty screen door. I understand the metal frame and its track needs to be removed and install a wood panel or similar to cover the still window's area. I do not want double wood door because the dogs may push and break the door stopper. Is that possible? If not, any suggestions to protect the sliding glass door from jumping or derailing from its track?
