[nyc] Dog Possibly Ate Rat Poison Left Outside My Apartment Door. Can I Hold My Landlord Responsible For The Vet Bills?

Location: NYC

I live in an apartment building in NYC, and I’m looking for legal advice about a situation that happened last night.
I discovered my dog eating a mysterious green substance on the floor directly outside my apartment door in the building’s common hallway. It looked like green rat poison to me, and I did not see the substance anywhere else in the hallway.
I immediately rushed my dog to an emergency veterinarian. They induced vomiting and administered activated charcoal to treat a suspected toxic ingestion. My dog was vomiting green material and is now on medication for the next 30 days. The veterinarian warned me about potential neurological effects if the toxin was not fully cleared.
The vet suspects rat poison but could not confirm the substance or identify the specific toxin. This made it difficult to determine the full extent of the potential risks. Thankfully, I got my dog to the vet quickly, and he seems to be doing better, but I’m still concerned about possible long-term effects.
The emergency vet bill is now over $1,000. I also collected a sample of the green substance, although it has not been tested or identified.
I contacted building management last night while the incident was happening and asked them to preserve the security camera footage and provide any recent extermination or pest control records that might explain what the substance was and how it ended up outside my door. As of now, management has not responded.
One additional concern is that, in a previous situation, my building refused to provide me with security footage and told me they could only release it to the police if a police report had been filed. Because of that prior experience, I’m considering filing a police report about this incident so that the footage may be requested before it is overwritten.
My main concern is that the substance was located directly outside my apartment door, and I did not see it anywhere else in the building. Other residents have dogs as well, so this potentially could have harmed another pet or a child. Given the specific location, I’m also concerned about the possibility that someone deliberately placed it there, although I have no evidence establishing that this was intentional.
I’m looking for advice on the following questions:
Landlord liability: Under NYC law, could my landlord or building management be liable for my veterinary expenses if the substance was placed in the common hallway by building staff, a pest control company, or another person, depending on the circumstances?
Police report and security footage: Would filing a police report be appropriate in this situation? Could the police request or obtain the building’s security footage, and what should I do to ensure the footage is preserved before it is overwritten?
Pest control records: Can I request records showing whether the building recently used rodenticide or other pest control products in the hallway or nearby areas?
Testing the substance: Would it be worthwhile to have the sample professionally tested? Would identifying the substance help establish liability or support a claim for reimbursement?
Recovering veterinary expenses: What evidence would I need to pursue reimbursement for the $1,000+ vet bill? Would small claims court be an option if management refuses to pay?
Possible intentional placement: If the substance was deliberately placed outside my apartment, what steps should I take to document the incident and protect myself and my dog without making unsupported accusations?
I have the veterinary records and bill, the sample of the substance, and my communications to management. I’m trying to establish what happened and understand my legal options before taking further action.
Thank you for any advice, particularly from anyone familiar with NYC landlord-tenant law or similar cases.
