I can see both sides of that - I tend to go for raising the fence but ideally I should make sure the dogs won't attack them!!
Yesterday when I was out in the garden with the dogs I heard a noise and there were 2 chooks standing right next to one of the dogs!! Poor Sparky (dog) was rooted to the spot looking at them in horror - I was in panic mode in case the other dog (Monty) came over from the front garden and joined the 'fun'.
What to do?
I used the only word that gets Sparky into the house ............ DINNER!!
Then I realised what I'd said - what an idiot!! So then here am I saying..... 'No Sparky not the chukkies for dinner - in the house for your dish - no, the Chukkies aren't dinner Sparky.......' I hope no-one heard me I must have sounded like the mad English woman!! Although that's pretty near the truth :-)
Anyway I dashed to the front garden, put Monty under my arm (they are Bichon Frises thank goodness, not labradors!) dashed back round to see if there had been a massacre - and there was Sparky sitting on the doorstep waiting for his dinner!
It's an interesting life here in France !
