Dog & Muddy Patch on Lawn

Thanks all, I hadn’t thought of fencing the patch off but that’s what I’ll do.
Great idea and Thankyou 😘

Our two cats go to a particular patch of lawn , very brown these days and they dig furiously and roll in it. Always the same part under a blue spruce. Very dry earth, it is like a grey powder. They love it and I just let them go because it gives them such pleasure. They remind me of hippos except it isn’t muddy, just dry earth. Animals are strange sometimes.

This is what I do every winter. It's inexpensive and easy to store when not being used. I ordered it online, I don't remember where from.
When the ground is wet the fencing pins can be pushed in without needing a hammer.

Fence that part off using wire or plastic netting or maybe a long lead to prevent the dog getting to that part.

I would either make a wire netting cage to put over it or flexible plastic type netting which would need to be raised above the muddy patch.
