Mr. Jones put copies of the following notice on trees and signposts around his neighborhood:

"Please help me find Rover!

Rover is a 70-pound, brown Golden Retriever-Boxer mix, last seen in this area on March 1. I will pay a $500 reward to whomever returns Rover to me safely. If found, please call 555-867-5309."

Ms. Smith was on a walk in the same neighborhood when she encountered a dog who had been hit by a car and had an injured leg. She took the dog to a veterinarian and paid $150 for treatment of the dog's injuries. Thinking that the dog was a stray, Ms. Smith decided to keep him as a pet.

The next week, Mr. Jones saw Ms. Smith walking Rover through the neighborhood. Mr. Jones explained to Ms. Smith that the dog was his and demanded that Ms. Smith return Rover to him. Observing Rover's reaction to seeing Mr. Jones convinced Ms. Smith that Mr. Jones was telling the truth. Feeling that returning Rover to Mr. Jones was the right thing to do, Ms. Smith agreed.

The next day, Ms. Smith saw one of Mr. Jones's signs for the first time and learned of the reward. She called Mr. Jones and demanded that Mr. Jones pay her $650$500 as payment for the advertised reward and $150 as reimbursement for the veterinarian's bill. Mr. Jones refused to pay Ms. Smith anything.

Your task: Discuss whether Ms. Smith is likely to recover any monetary damages from Mr. Jones. Deal both with the $500 reward and the $150 veterinarian's bill. For both, explain what grounds Ms. Smith might assert to support her claims and state a conclusion about whether Ms. Smith will be able to collect the amount in question, clearly stating the applicable legal rules and explaining how these rules apply to the facts of this case.
