My tenants want a dog - what do i need to consider and put in the lease?

[Elena Pech]

My tenants, a nice young couple, want to get a dog. They've been a year in the apartment and everything is fine so far. They say that they both were raised with the dogs and are experienced. I have no experience with dogs, and prefer no dogs on the property. However it looks like there is a high demand on home pets now, and I think I have to consider it. What do I need to worry about? What should I mention in the lease about their pet?

It's hardwood and tile floors in the apartment. No carpet.

Do they need to buy any dog insurance with dog bites coverage or anything like that?
Should I mention that in case the dog create problems and I get complains from the neighbors, the lease won't be extended or can be terminated? (or it's impossible to execute?)
Are there specific breeds or parameters that are recommended, or specifically not recommended?
What should I worry about and specify in the lease regarding the dog?

I charge a $500 pet deposit per pet, $250 is non refundable. You can also charge pet rent, it is typically $25 per pet/month.
