Suggestion/Help

Hello po friends, our dog has been excessively scratching for the past 2 days. Kaka groom lang po niya and she has no visible fleas/ticks. What we’ve noticed po is mga area ng body nya na may mga patches of small scabs. What can you recommend po na home remedy to temporarily ease the scratching? Right now, we’re in place na wala kaming access to a vet clinic or pet store. Any suggestions would be a great help po.
