Photo of garden & Northern Inuits imprint! HELP!

Does anyone have any advice or some use of barrier to prevent dogs getting into a section of garden?
Here are my two Northern Inuits's giving little respect to the grass which once was! My landscape garden now looks like a mudbath and they come in looking like they have been in a swamp.
I am going to have to section parts of it off, these photos are only part of the trouble.
Does anyone use any type of barracade or gate? I dont really want a permanent structure maybe something I can open and close so as to allow them the full stretch of the garden If Im there, but when letting them out for a quick wee I can have them closed in to the patio. I had thought of a folding gate, like those you put up for climbing roses etc and the metal ones they put at porch entrances to shops but am sure they would be expensive.
Any help would be appreciated, as you can see I have little grass left.

OMG Miss Kirkham, what have they been doing up there, no the wonder you are fighting a losing battle against the mud. You need something thats for sure.

Thanks Janet it was once lovely up there, spent loads of money putting in all those plants and they dug them all up. Im gutted. What you doing up?

I know you will have to start again. i know how you feel, remmber when our fence blew down last year, you would of thought a bomb had dropped before we tidied it all up, but you do have a much bigger garden however.
i was on my way to bed actually, i just was looking tosee if anyone had answerd my sad post in gone but not forgotton. i read a bad sad stroy yesterday and wish i hadnt,it has played on my mind all day and i wnated to try and give it "closure" as they say.
