Any ideas you have will be appreciated. I've already gotten good ones, like keeping things in place. One question I have...how to scent his outdoor kennel so he can find it. Every evening I let them inside through a door at the front of the house, feed them, then take them out the back door into our fenced backyard, through that gate, and out to their kennel for the night. He has no way of knowing if the yard gate and the kennel door are opened without bumping into them. I can scent the house doors with vanilla, but I can't think of any way to scent or otherwise mark the gates. Thank you in advance for any advice!
