Oxybuytrin

Is Oxybutynin dangerous to dogs? I am not sure my dog ate a pill, but I did drop 1 or 2 on the floor. I found one. My 6-month-old spaniel/lab mix is about 30 lbs.

Actually, depending on the milligram strength, a dog this size wouldn't be adversely affected by one pill.  Of course, just as with people, there is always the chance that the dog could experience a side effect, but generally speaking, one pill of, say, the 5mg strength wouldn't hurt the dog.  Oxybutynin is an anticholinergic drug that is actually used in dogs to treat urinary incontinence.  It doesn't work on the actual bladder sphinter, it works by relaxing the bladder muscle so that it is able to store more urine without feeling full.   If the dog were to ingest one, there should be no ill effects.

That is NOT good for your dog.  Watch for any odd behaviors, and be ready to go to the vet at anytime.

What is the milligram strength of the oxybutynin?

You need to call your Vet, the ER clinic or Poison Control.
Maybe someone else can answer this but I am not familiar with that med and hesitate to advise on prescription medications anyway.  
I did look it up and guess it is given to dogs but one study showed dose related tachycardia and hypotension.
I would call and ask someone.
