I must say I am rather unused to having a dog around the house myself. My last dog, a boxer, passed about 4 years ago and today I've got a 3 year old rather rambunctious Siamese cat.
However I watched my sister's 4 month old puppy last week for a few days. A 'bug'.. a Boston Terrier, Pug mix. He's only about half the size of the cat and surprisingly my cat let him play rather aggressively with him.
To the heart of the story, I was so unused to having a dog around that within a few hours I noticed that my place 'smelt of puppy' and I didn't really like it. Not that the pup had urinated or soiled my place at all, just the smell of a dog in the house was so odd to me after these years I just didn't like it. I should have given that pup a bath.
