There are two reasons your dog might be flaky after a bath, if they weren’t flaky beforehand:1. There may be shampoo residue left behind. As well as you think you rinsed your dog, it’s possible to leave a little shampoo behind, which will become flaky and may irritate your dog’s skin. Try rinsing your dog again without shampoo and see if that helps.2. It’s possible that the shampoo itself dried out your dog’s skin. If you rinse them again and they’re still flaky, you should try a different shampoo next time, maybe one with oatmeal or another moisturizing agent.If your dog is always flaky, regardless of their bath and shampoo routine, they may have dry skin, allergies, or a more serious medical condition. If a moisturizing shampoo doesn’t help, try adding fish oil to your dog’s diet or changing their food entirely. Food allergies are more common than you might expect. If nothing seems to help, it’s time for a trip to the vet.
