What to Do When Your Neighbor's Pet Invades Your Home: Rights and Guidelines

You open the gate and find your neighbor's dog in your yard. Or you find cat feces in your garden, without ever having had a feline around. For many homeowners, this is a common—and frustrating—situation. But when neighbor's pet invades your house, what exactly can (and should) you do?

Situations like this require more than just outrage or complaints within the condominium group. They require action based on dialogue, respect, and, if necessary, legal support. After all, the problem isn't always the animal itself, but rather the owner's lack of responsibility.

Do you know your rights — and the limits of what you can and can't do when your neighbor's pet gets into your yard?

Why does this happen so often?

Many owners underestimate the risks of letting their pets roam free. Dogs that jump walls or cats that roam rooftops seem harmless until they start causing real nuisances for neighbors. Some common reasons for this type of invasion include:

• Poorly installed gates or fences
• Lack of supervision during walks
• Animals raised free-range, without restraint
• Negligence with automatic gates or open areas
• Negligent or absent guardians

The result ranges from destroyed plants to feces, barking, scratches, fights with your pet or even bite risks.

And when the discomfort repeats itself, the discomfort turns into conflict.

What are the rights of those who have had their space invaded?

The Brazilian Civil Code, in its article 936, establishes that an animal's owner is responsible for all damages caused by the animal, even if it runs away or acts unpredictably. This includes invasions, soiling, scratches, fights with other pets, or even more serious situations.

Furthermore, Article 1,277 of the same code guarantees the right to peace and security of private property. In other words, no one is obliged to tolerate constant invasions or disturbances caused by animals from other homes.

If the neighbor's pet invades your house, you have legal support to:

• Request compensation for damages
• Demand that action be taken
• Record occurrences in repeat cases

But, in practice, the best way out always starts with conversation.

First steps: talk to your neighbor

Before taking any formal action, it's best to contact the animal's owner and explain what's happening. Often, the owner may not even realize their pet is trespassing on other property.

Speak calmly, explain the disruption, and suggest solutions, such as reinforcing fences, using a collar, a screen, or changing the gate.

Example: Carla noticed that her neighbor's dog was coming into her yard every morning and scaring her cat. After talking to the neighbor, he admitted that the gate wasn't closing properly. He installed a lock, and the problem was resolved without further conflict.

What if talking doesn't solve anything?

If the guardian is negligent or unwilling to resolve the issue, you can:

• Record images or videos of invasions (as future proof)
• Talk to the building manager, if it is in a condominium
• File a police report in more serious cases
• Notify the neighbor in writing, with delivery record
• Contact the city hall or zoonosis agencies, if there are risks to public health

As a last resort, it is possible to file a lawsuit for moral or material damages, especially if there is proven aggression or harm.

What if the animal causes harm or injures someone?

The responsibility remains with the owner. This applies to both animals released into the street and those invading other homes.

If a neighbor's pet bites, scratches, or injures someone on their property, the owner may be held civilly and criminally liable. This includes paying medical expenses, compensation, and even fines.

Statistics from the Brazilian Institute of Geography and Statistics indicate that 70% of accidents involving pets occur within residential areas — often due to negligence on the part of the owners themselves.

Can I prevent the animal from entering?

Yes. You can take containment measures within your home, such as reinforcing gates, installing screens, using safe repellents, or even changing your pet's routine to avoid direct contact.

However, never use poisons, traps or any form of aggression against the animal, even if your pet frequently invades your space. Besides being a crime of cruelty, you may be held liable for damages to your pet.

The problem must be resolved responsibly and legally.

A clear analogy: the pet as an uninvited visitor

Imagine if, every day, someone from next door came into your living room, messed up the couch, and left as if nothing had happened. Would you get used to it? No.

With animals, the logic is the same: just because they're cute or "just want to play" doesn't mean they can roam freely in other people's spaces.

The house is a physical and symbolic boundary — and it needs to be respected.

And when the problem is recurring in condominiums?

In buildings or gated communities, the situation should be reported to the administration or building manager. Many condominiums already have clear rules regarding animal movement.

When they are not complied with, guardians may be warned and even fined, according to local convention.

Repeated offenses may lead to more severe measures. Therefore, it's important to record all incidents in writing, including dates, times, and evidence, if possible.

Conclusion

When the neighbor's pet invades your house, the situation may seem minor at first—but it quickly becomes a problem for coexistence. Knowing your rights, maintaining open dialogue, and taking legal action when necessary are ways to protect your space without compromising the animal's well-being.

Remember: the owner is truly responsible. The animal is simply following its instincts, and it's up to the human to ensure safe and respectful boundaries.

And you, have you already talked to your neighbor constructively or are you waiting for the next scare to act?
