Instead, individual localities are tasked with enacting their bylaws. So, regarding how many pets you can own in Maine, the simple answer is it depends on the animal control laws in your city, which may be lenient or very strict.
In most Maine cities, keeping more than 3 dogs is deemed to be a nuisance. Cat ownership, on the other hand, is not often regulated. It’s best to check with your city clerk or local animal control for specific laws regarding pet ownership. On the other hand, you can conduct a search online for your local animal ordinance.
Meanwhile, I've listed some Maine municipalities and their pet limit laws below.

Are there any dog breeds banned or restricted in Maine?
Maine is one of the few states that do not allow breed-specific legislation (BSL). Nevertheless, many cities and towns in Maine have dangerous dog laws. However, unlike BSL, which focuses on specific dog breeds, a dangerous dog law focuses on any dog with a known propensity to attack unprovoked.
