Would my dog tripper remember me?

Would my dog Tripper remember me after almost 4 years ? I havent seen him and I dont think I will ever again but if I did would he respond to me if I would call his name. Cause ever since I have seen like 6 dogs that look liek him and only 2 dog have had floppy ears like him. But I saw another 1 at the park and he had floppy ears but he was too big but I thought he might have grown over 4 years cause he was around 5 or 8 years at the time. So I caleld his name but he didnt respond but he looked around like looked from side to side. Do u think that was him?
And do dogs remember there owners?
Tripper was a blue male cattle dog.

There are stories of extraordinary dogs that remembered people over long periods of time so it's very possible he would remember you. Cattle dogs are smart so that might help. I don't think the dog you saw was him. If he recognized you or your voice, he would have come running to you.
