Help please with this plant

Hello,
I have a few of these in my garden and normally at this time of year they have a blue colouring but this year they are turning brown and falling off. Can you please tell me what is going on with them and how I can help them. They are about 8yrs old

 

I'm not sure, is that a juniper?
I'd just prune out the brown bits. the blue bits will eventually cover those over.

Looks to me like a cat or dog pee problem.

 

Yes Pete they are junipers and you are so right, my jack russel dog has a habit of peeing there, thanks for replying
