On arrival at this site there was no-one about so we knocked on the door of the house and spoke to a gentleman. We asked him where we should park our motorhome as we had recieved a confimation email we were booked on. He advised us that as we did not require ehu we could go anywhere we liked, so as we were there to fish, we parked and set up by the lake. About 2 hours later a lady came with three dogs one not on lead ( states clearly that campers dogs MUST be on leads which ours was) which came over to have a go at ours, but she managed to recall it. She then said I hope you are not planning to park here for the night? to which we relayed what the gentleman had told us, and we were all set up. She said ok and would be down to see us later without these (dogs). A few hours later we were fishing with our backs to the motorhome we heard a commotion and turned to see the owners dog set upon our ten year old dog who was on her lead and no eacape. We ran and chased it away, it was with the owners daughter on the golf buggy and out of control. We just held our hands up to say, what the hell? She said sorry. Our little 10 year old dog was covered in saliva and hurt her leg trying to get away. She was trembling for hours, We immedietley packed up and were off first thing next morning to the vets. wher she was diagnosed with a ruptured cruciate ligament. £2000 operation and 12 months recovery, which due to her age we are reluctant to put her through. I had an email the next day from the owner to see if we were coming back and if we needed ehu. I told her what had happened (which went to her i phone and was read) but did not hear anything till the next day with an apology, that her daughter had forgotten to put them on leads.
