My 2 dogs (2 and 6) were housetrained quickly and easily. This week for no reason that I can tell 1 of them is pooing during the night ...I dont know which yet as they sleep together and eat the same sort of food! Neither seems ill atall and both seem sheepish about it, although I havent shouted at them. Its so horrible though and very time consuming keep scrubbing with washing powder to get rid of smell.
Can anyone hel

If this has only just started there must be a reason. And I would think it was either a medical problem or they are not going where or when they usually do because something or one has frightened them or caused them to be concerned about going where they normally do. Some dogs can be put off going simply by the long grass they usually use being cut.

So first put the think cap on and see if you can think why one of them is not emptying as normal and if you can not think of anything then perhaps a word with the vet.
