Hi there, you are through to Dr Linda.

What age and breed is your dog?

Is the dog clinically well; no other concerns?

Any medical history or is she on any medication at the moment?

Can you describe the poo in more detail- is it runny or solid, is it dark brown or black and tarry?

How long has this been going on for?

Finally, what diet is she on (including and treats/titbits) and does she receive any supplements?

Customer: replied 14 days ago.
My dogs seems okay but a little more needy/ demanding to go out than normal.
Poo is darker and feels harder.
He’s fed royal cannon and poo used to be slightly darker than the food (light brown) but is now grey/ light black.
Eats and drinks okay.
He’s not a scavenger and doesn’t eat anything but his own food. Has been know to chew up his bed and get the stuffing out but yet to see if this has been ingested as none has been passed.

Ok, thank you for this information.

It may simply be that the poo has less moisture content than before so appears darker. This can happen if a dog is drinking less, exercising more or if the weather is warm/humid.

As he is quite well and with no other symptoms (such as weight loss, vomiting, diarrhoea) there is less chance it is something sinister.

While darker stool can sometimes indicate digested blood in the stool, we would normally have other symptoms such as diarrhoea, vomiting, pale gums, lethargy or reduced appetite.

Royal Canin is a good quality food and I would continue with it.

I would ensure he is up to date with a good quality wormer such as Panacur or Drontal.

I would see if increasing the amount of water he gets helps. This may mean adding water to his dinner or encouraging drinking by offering e.g. the water that chicken is boiled in.

If the problem continues or if he develops other symptoms, the next step would be a couple of simple diagnostic tests to ensure there is nothing more worrying going on. This would normally mean a simple blood test to ensure he is not anaemic and a faecal exam.

In an older dog, we may also consider abdominal imaging (especially if there is evidence of anaemia).

It's also sensible to ensure there are no potential toxins about he may be getting to, such as rat bait in the garden or human medication within the home.
