My partner and I have been living together for 5 years now we have a 2 year old and a new baby on the way . When we started living together she had a big dog before she met me . At first i didnt mind it but as time went on it started to bug me because of the smell of the house inside and the dog hairs everywhere. He is a large rottweiler and he sheds hair everywhere i find big clumps of hair on the floor. He also rubs himself against the wall and stains it. I wouldnt say im a clean freak but to me its just unhygenic and having our children growing up around this is a problem for me. Iv asked her before to put the dog outside in a kennel but i only managed to get him barrred from upstairs. He sleeps downstairs in his bed . When i come home from work i am met with a dog odour as soon as i walk in the door. It annoys me straight away. She gives him bones and after a day or two they smell really bad. I recently had a friend stay over and Iwas saying it to him about and he agreed with and said the smell was upstairs aswell and he was only saying it me as a friend. My family have also said it to me about the smell and that its not very good for a new baby. My partner thinks the sofa smells only because we have a fabric sofa and says when we get a new half leather sofa it wont be as bad . I dont know what to do. How can i convince my partner how bad and unhealthy it is ?
