(perhaps we ought to start a pet section in the forums)

So my dog Roxy is working with her buddy Joey (neighbors dog) to dig under the fence between our yards! Their both large dogs (she's a 70+ pound pitt and he's a 100+ pound boxer) so we've been able to find the holes and fill them before they get them big enough for either to slip through.

Here's our concern though - they play well when their on different sides of a fence, but when we put them together in the same yard they will fight after a few moments. How do we get them to neither stop fighting when their together or stop digging?

Don't leave your dog unattended for long periods of time in your garden. Or, you could buy some slabs and lay them in a row along side your fence, that way she has concrete beneath her feet and hopefully wont start digging under the slabs.

Haha I'm sorry, but that's amusing! I can just imagine both dogs digging their way under the fence with the music from The Great Escape on in the background ;D

How old are they? My dog was terrible for digging when she was younger but now she's ok. As for the fighting... I dunno. Dogs just sometimes like to show each other who's boss.

ack * Either stop fighting or digging.

Hmm, never had either one of those problems with my dog. I guess as Transit said, don't leave you dog outside for too long, possible glance out the window occasionally to make sure she's not digging, if she is, then have her come back inside. The slabs thing was a good idea though however I can imagine if she can get her paws at the edges of it possibly move it so you may have to keep an eye with that.

Could you try maybe spraying something on the fence?
Like something with an odor but isn't harmful?

I think they make sprays like that for couches and stuff.
They don't smell to everyone, but they smell to the dog or something.

Look and see when they fight, if they are wagging their tails, because then that means they are just play fighting. When my dog met my sister's dogs they started fighting, but then after about 5 minutes they started wagging their tails. Maybe try cementing under your fence, so then they can't claw through it.
