Pekingese Life

My 2 pups were licking their paws quite often. I checked them and there was nothing that I could see .
During a check up to the vet I asked if anything was on the skin. After examination all paws were fine and normal.He said it could be allergies to the floor cleaner product since it contains chemicals.
I decided to switch from my regular cleaner to white vinegar mixed with warm water.(1:3)
It’s been 6 months and both of the pekes aren’t licking their paws anymore.
For their comfort and health I will keep using the vinegar mix.
