The family of Lady Gaga's dog walker has thanked the singer for her "non-stop love and concern" after he was shot four times during a dog-napping in Los Angeles.

Ryan Fischer was hospitalised after he was attacked by two men as they took two of Gaga's French bulldogs on Wednesday evening.

Mr. Fischer is expected to make a full recovery.

In a statement thanking family and friends, his family said, "We cannot possibly say enough to thank all of the first responders, nurses and doctors who have worked so tirelessly to care for Ryan.

"Of course, we also want to thank Lady Gaga who has shown nothing but non-stop love and concern for Ryan and our family right from the outset.

"Ryan loves (dogs) Gustavo and Koji as much as Lady Gaga does, so we join in her plea for their safe return."

The two stolen dogs were later recovered unharmed after an unidentified woman brought the dogs to a Los Angeles Police Department station on Friday evening, The Associated Press reported.

Representatives for Lady Gaga were then able to identify and return the dogs.

It was unclear how the dogs came into the woman's possession but detectives say she was "uninvolved and unassociated" with the dognapping.

Gaga commented about the attack publicly for the first time over the weekend and confirmed the $500,000 reward that has been offered for the safe return of the dogs.

"If you bought or found them unknowingly, the reward is the same. I continue to love you Ryan Fischer, you risked your life to fight for our family. You’re forever a hero."

The suspects remain at large while the police investigation continues.
