We've used our portable doggie yard at the fort with no problem. I think the most important thing to remember is that you must be with your dogs while they are in the doggie yard. You CAN'T put them in it then leave.
We leave our pups in the motorhome when we are gone. We put them in the doggie yard when we are at the motorhome and are in and out or are relaxing outside under the awning.
Oh sure. I absolutely would never leave my puppy dog and go. I'd be so afraid that someone might take him as we've had a problem with that in our area.
Yes that will be just fine! I looked at thisat Tractor Supply as an add on to my little fenced are for mine. But, then I remembered she is old and doesn't like being outside anymore.
