tenants with pets

I wonder if you could have a clause in a lease that requires a certain amount of time with a dog trainer...
Dogs are great, but lots of people are just stupid about what they need.

I have a tenant with a large dog and asked a neighbor to call me if he hears or see's anything worth reporting. So far I've heard nothing.

On a slightly different note, I own in a 12 unit building where 90% of the other owners have dogs. I have two small dogs- one is perfectly trained and healthy and exceptionally good. The other was a rescue dog and has gone through therapy, gets regular anti-depressants, and needs walkers to pop in on him twice a day. If I didn't take the dog he would have been put to sleep, and he's actually very sweet and it's not his fault he was beaten as a puppy so I took him! Since then I have had nothing but complaints from people above me who have a screaming yelling child (I work with babies and this is no normal screaming), a young couple next door who pump music extremely loud and smoke pot in the alleyway between our units, and a young caribbean girl who's mother (?)enters the building at all hours screaming and yelling in the hallways and mutters "white bitch" when I say hello.

These kind of things are relative. While someones dog barking when a bell is rung may be unacceptable to one person, you may not even notice it. I say give this person a trail basis. Let them know you'll be watching them very carefully.

I believe that 311 can be anonymous, but again folks, if you sense that any animal is being abused (such as being left out all day and night without proper shelter, food, or water) you need to make a call. One phone call could save an innocent animals life.
BTW- complaining to building managers are pretty useless. As long as the checks come in, they couldn't care less. Chances are they don't even live there.
