Doggy dilemma

Hello, just wondering what others think. Sorry this will be long. Waited many years to move to a new residence. Found a place. Great suburb. Gated & safe community. Rent we can afford. Passed the first interview. They said the community would be delighted to have us. Then invited us to a second interview to meet the people & property Manager/Owner. Down came the guillotine! You are allowed only one pet. A dog or cat. I told them I have a dog. Already shaking in my boots about my daughters new puppy (one month owned) I froze did not mention her. They asked my dogs breed. They asked her size. I said Medium. They asked her weight. I said guessed about 13-14 kilos. She is my emotional assistance dog (EAD). They said does she have papers to say EAD. I said yes can provide. They said is she well behaved as in does she bite or bark a lot. She is quiet. She has never bitten. (still afraid to mention yappy, petite puppy) They said they needed 3 weeks to consider as my dog is too big! 3-4 kilos over their acceptable weight. They told me I'd have to put her on a health regime to lose the extra as no pets over 10 kilos allowed. We have a third & final interview to sign contract filled with rules. It says breaking any rule results in immediate eviction. Daughter says lets just sneak puppy in. Say nothing. I don't wish to pack, pay removalists, arrive and then risk getting turned away on the side of the street. This was to be our dream home. We saved. We waited ages to find the right fit. So many people in family have different opinions on what is best to do. How to proceed. I'm thinking honesty upfront is the best policy before signing or moving. Others do not. I'd appreciate any suggestions.

One pet means one pet. The other tenents will figure out the extra dog soon enough, you don't want an eviction on your record. The puppy can be re-homed, and it's only been in your possession a month. More importantly, I would wonder if losing a third of your dog's body weight would actually be healthy for him/her. Maybe this isn't the place for you.
