What Causes Dog Itchy Skin?

1. Environmental Allergies

Dogs can develop allergies to:

• Pollen
• Grass
• Dust mites
• Mold
• Household cleaners

These allergies often cause:

• Red paws
• Ear infections
• Face rubbing

2. Food Allergies

Some dogs react to certain proteins or ingredients in food. Common triggers include:

Even one flea bite can trigger intense itching in sensitive dogs. Common parasites include:

Cold weather, low humidity, overbathing, and harsh shampoos can dry out your dog’s skin. Signs include:
