Our field has 5-6ft fencing. 98% is 6ft, with only a small portion near the gate being 5ft. It has chicken mesh on the lower half, so no sneaky terriers should be able to get out. This also limits wildlife to the odd bird or vole, which usually make themselves scarce quickly.
You will be the only occupant in the field so it is suitable for reactive dogs or dogs that just enjoy their own space. We have a number of parkour obstacles for your dogs to explore, as well as dog friendly plants and herbs.
