Thank you to everyone that helped find Apollo. The "Nextdoor" app was a leading contributor in our reunion but I would recommend this site, Nextdoor, post on your local Facebook pages, and do a pawboost. All of these posts helped spread the word that Apollo was missing and ultimately is why he was found. The sharing of the Facebook posts by many people is what lead to me finding his found post on Nextdoor and contacting the friend he made that picked him up.
