One of my dogs had dire rear last week which cleared up after a few days and now the other one has it.  I have a feeling it is just down to random scavenging but was wondering if dire rear is catching.

If it is caused by an infection then it most certainly is.

Agree with Nova.  If it's something like Giardia or Campylobacter, definitely.

Warm weather increases likelyhood.

> dire rear

lol is that a ploy to beat the gruesome adverts !!

Thanks, I will keep them away from other dogs until it is cleared up.

the 'dire rear' worked with the adverts as I still have fish 4 dogs and fleecy harnesses at the bottom of my page!

> worked with the adverts

So what does that have to say about The Kings Head, Accommodation, South Wales at the top of the page.

No idea, I am at work and don't have any adverts there.  I doubt I would get Welsh adverts anyway.
