Hi, I rehomed a unneutered spaniel about 4 months ago. It took a couple of weeks of house training back to basics before we stopped having accidents in the house, but after that all was well. A few weeks ago we spent some time with my parents and their bitch. There were definitely some competition for top dog and both dogs had accidents in the house during that time (they were marking). Since we got back home, about 75% of the time I come downstairs to a poop in the living room. Sometimes there is a wee too, not always, and mostly the wee appears to be marking as its small and/or has been up the curtains. I’ve read that dogs don’t generally mark with poop so I’m at a loss why this is happening. He can clearly hold all night as he is only 3 and we had no problems before this and haven’t changed his routine. I’m feeding him his last meal at about 5pm, followed by a 45 minute walk at about 5.30. On that walk without fail he does at least 1-2 poos. He’s let out into the garden last thing at night but only ever does a wee (with lots of encouragement). I’m being careful to restrict how many treats he gets now on his evening walk and I’ve stopped giving him a chew when I have my dinner. We’re told not to rub their noses in it so when he messes he gets told ‘no’ and is essentially ignored for an hour and obviously I praise and reward him lord when he poops on walks. I can’t shut him in a smaller space at night as he has isolation anxiety, so he sleeps in the living room but has free access to my room. The problem is he has no inclination to tell me when he does need to go out. Having spoken to the vet, he’s now booked in to be neutered in a few weeks time in case it is marking, but is there anything obvious that I’m missing?!
