My dog poos on his snuffle mat that's green and also a green blanket we have. Absolutely nothing else, ever. These purchases are only within the last few weeks and we have had him 3 years. Surely he isn't thinking this is grass?? He's been fully house trained since he was some months old and we haven't had an indoor accident since 6 months until these 2 green items! I've removed them now... obviously! But find it really strange and wondered if anyone else knew the reason/had experienced similar
