Understanding pet allergies
Just like us, dogs and cats can react to foods, parasites and things in their environment. Allergies often show up on the skin and ears, but some pets also have digestive or respiratory signs. Spotting issues early helps you prevent ongoing discomfort and secondary infections.
Common types of pet allergies
1. food allergies
- Typical triggers: Specific proteins like beef, chicken or fish, and sometimes wheat or dairy
- Signs: Itchy skin or ears, recurring ear infections, licking or chewing paws, vomiting or diarrhoea
- Management: A structured elimination diet and re-challenge under vet guidance
2. Environmental allergies (atopy)
- Triggers: Pollens, dust mites, mould and grasses
- Signs: Persistent scratching or licking, red inflamed skin, sneezing or watery eyes
- Management: Washing after outings, topical care, antihistamines or vet-prescribed therapies
3. Flea allergy dermatitis
- Trigger: Reaction to flea saliva
- Signs: Intense itch, hair loss and red skin over rump, tail base and back
- Management: Strict year-round flea control for all pets in the household and home treatment when needed
4. Contact allergies
- Triggers: Shampoos, detergents, some fabrics or garden plants
- Signs: Localised redness, rash or itch where contact occurs
- Management: Avoid the irritant, rinse off residues and use gentle, hypoallergenic products
Spotting allergy symptoms
- Excessive scratching, licking or chewing
- Red, inflamed or scaly skin; hot spots
- Frequent ear infections or head shaking
- Digestive upset like vomiting, diarrhoea or soft stools
- Sneezing or watery eyes
If these keep popping up, it is time for a vet visit to find the cause and prevent complications.
