I recommend " ts2searchforlostpet " on Instagram to you. They track both pets and livestocks with chip and those that are not. They found and brought back my Ziko.
Please come to ACCT Philly and do a walk through and file a lost dog report. 111 w Hunting Park Ave. 10-6 daily
If the dog does not have a chip or tags you should do this every 48 hours.
