Virginia: the agent refusing you probably holds a licence
Most refusals in this state come from somebody who manages property for a living, and people who manage property for a living answer to a regulator as well as to their client. That is a quieter kind of pressure than a complaint, and it works earlier.
Two things are happening at once
One is the housing question, which Virginia Fair Housing Office and Region III - Philadelphia deal with. The other is a professional obligation carried by the individual writing to you. Naming both, politely, in a single sentence changes how quickly the first one gets answered.
Who signed the letter matters here
The same refusal carries different weight depending on who put their name to it.
How to use it without threatening anybody
Nothing here calls for aggression, and aggression tends to harden a position that would otherwise soften. What works is a single neutral sentence asking the recipient to confirm, in writing, that they have considered the request and to state the basis for the answer.
A professional reads that sentence differently from an ordinary correspondent. It signals that a record is being kept, that the record will show who decided what, and that a refusal without a stated basis will be visible later.
It also gets you something useful whichever way it goes. Either the answer changes, or you receive a written reason that can be measured against the only three things a refusal may rest on: what your own animal has done, spending shown to be excessive at that address, or an adjustment big enough to alter the way the property functions.
Keep it to one sentence. A long letter invites a long argument; a short request for the basis of a decision invites a decision.
Five lines that do the work
Nothing longer is needed, and anything longer tends to weaken it.
A commonwealth of very different markets
When the polite route runs out
If the written request and the one-sentence follow-up produce nothing, Virginia Fair Housing Office handles the housing side and Region III - Philadelphia runs alongside it federally. Neither charges a fee and neither expects you to arrive with a solicitor.
Address it to the entity that owns the property as well as to the agent. Title is a public matter, the duty travels with it whoever is employed to administer the letting, and proprietors are frequently unaware that anything was refused at all.
Rent should keep going out on time throughout. Stopping it is the fastest way to hand the other side a reason for eviction that has nothing whatever to do with the animal.
