If you notice your dog constantly licking, chewing, or scratching themselves, especially in specific areas like paws, ears, face, and belly, it could indicate an allergy.
Allergies often lead to skin problems in dogs. Look for redness, rashes, hives, or hot spots on your dog's skin. These skin issues can be quite uncomfortable and might lead to secondary infections.
If your dog frequently develops ear infections, it could be due to allergies. Allergic reactions can cause inflammation in the ears, leading to itching, redness, discharge, and a foul odour.
Some dogs with allergies might experience gastrointestinal symptoms such as vomiting, diarrhoea, or increased flatulence. These symptoms can be caused by food allergies or sensitivities.
Dogs can also have respiratory allergies similar to hay fever in humans. If your dog frequently sneezes, coughs, wheezes, or has a runny nose, it could be a sign of respiratory allergies.
