What a shame...it must spoil your walk if you have to keep a look out for those labs! I must admit I squirted the Rotti with water when it went for Chris' puppy Logon, poor Logon did not know what to do, bless him.
A German Shepherd frightened Elsie Grey on the beach and she looks very worried when we see one now

Also poor Daisy May has been attacked twice by a Staff ( & the owner just said I did not know there were any other dogs about!!) We were in a field and Daisy May only got away because she is so fast!
She was also attacked quite badly by a Japanese Akita....that just flew across the field out of the blue and jumped on her back....she was just playing with Elsie grey!! No warning and the bloke just sauntered over and did not attempt to control his dog!!!

I shouted at the dog in my best teacher voice and he let go, but poor Daisy May was still screaming

Best I don't repeat what I said to the man and I had to stand up on my tip toes to look him in the eye......
Oohhhh dear...I do believe I have been ranting away here....sorry
Anyway, I do hope your darling Deeries do not have any more trouble from those labs
