Can you tell the difference?

OK I know, you are fed up with goats and dogs! But look how similar they are! When viewed by Brian from the verandah into the paddock!
He counts 16 heads - 14 goats 2 dogs - and sighs with relief.
Kaz is the nearest. Pol is in charge as usual. He is a real good worker by himself but likes Kaz to be with him most of the time. Always at night. Now they are in this paddock it is near to our bedroom window and they spent most of last night making friends with the dog next door through the fence. Very noisy as dawn broke. What with the birdsong too. Lovely though it is!
