blocking flies from coming inside
OK, the weather is getting nice and I want the door open to the yard so pup can come and go. Problem; the flies also come and go. I used to keep them out with a bamboo bead curtain but having this pup I foresee some damage.
How do you guys all solve this? What material, what works etc? Remember it has to be somewhat puppy proof.
PS: I know that ideally I should supervise and supervise and clickering him when he goes through the curtain without taking parts with him etc. but it is not always practical.
