Tenant wants to get one more dog

[Frida B.]

Hi! We rented to a tenant with 3 (Older) dogs. They’ve signed a years lease stating no additional pets. One pet passed away. They still have the initial 2. They have 4 months left on Lease and want to get another dog (not a puppy) probably 1 or 2 years old. Any thoughts on how to handle this would be appreciated. Property is in California.
