What might this be on dog's foot?

not sure if this photo will upload but anyone know what this might be - just discovered it ? Interdigital cyst? Is this a vet visit?

 

Sorry, we can't see a photo. Maybe a trip to the vets is best.

 

When in doubt, the vet is always my first point of call

 

From experience any lumps/bumps should be investigated early. Keep us posted.
