Why they appear on paws, ears and skin - and what's really behind them
Yeasts are part of the normal skin and mucous membrane flora of dogs. They only become problematic when the natural balance is disturbed and they multiply excessively.
What exactly are yeasts in dogs?
Yeasts like Malassezia occur naturally in almost every dog. In a healthy organism, they are kept in check by the skin barrier, immune system and microflora. If this interaction becomes unbalanced, yeasts can begin to multiply significantly - and cause problems.
It is important to note that yeasts are not an external infection, but rather a sign that the dog's internal and external environment is not stable.
Typical places: ears, paws and skin
Yeasts prefer warm, humid and poorly ventilated areas. This is why problems appear particularly frequently:
ears
- Head shaking and scratching
- Redness of the ear canal
- dark, greasy secretion
- unpleasant sweet-musty smell
Paws
- intense licking or nibbling
- reddened areas between the toes
- brownish discolouration of the fur
- recurring inflammation
Skin & skin folds
- itching
- oily or flaky skin
- dark skin discolouration
- Hair loss in individual areas
These symptoms are often similar to allergies - which is why yeast problems are often misclassified.
Why yeasts can get out of hand
The causes are usually multifactorial. Often several factors play a role at the same time:
- a weakened skin barrier
- recurring moisture (e.g. swimming, rain, skin folds)
- Stress or illness
- Medications such as antibiotics or cortisone
- feeding that is not optimally coordinated
None of these points alone fully explains the problem - what matters is the interaction.
The role of the intestine and immune system
The intestines and immune system are closely related. An unstable intestinal flora can influence the immune response and make the skin more vulnerable. However, this does not mean that yeast “migrates from the intestines into the ears”.
Rather, the following applies:
- If the immune system is permanently challenged,
- Control of yeasts can be lost locally.
The intestines are therefore part of the overall picture, but not the sole cause.
Feeding: an important component, not a panacea
Diet influences skin, coat and immune system. Problems often arise when:
- the amount of food does not match the activity level
- the food is poorly tolerated
- very heavily processed products are fed permanently
- frequent, unplanned food changes occur
However, extreme approaches such as radical diets or blanket bans on individual nutrients are not effective and can put additional strain on the dog.
Why external treatment alone is often not enough
Ear cleaners, paw baths or ointments can relieve symptoms - but rarely solve the cause. If the inner balance remains unchanged, the problems often return.
It therefore makes sense to take a holistic approach that takes care, feeding and individual stress into account.
Conclusion
Yeast problems on ears, paws or skin are not a sign of poor hygiene or an isolated problem. They show that the balance between skin, immune system and nutrition is disturbed. A calm, informed approach is more effective in the long term than quick fixes or extreme measures.
Frequently asked questions
Answered briefly and understandably
Are yeasts contagious in dogs?
As a rule not. Yeasts usually arise from an unfavourable skin environment or a weakened immune system.
Can food promote yeasts?
Yes, the skin barrier can suffer if there is intolerance or unbalanced feeding. An adapted diet often helps.
Advice tailored to your dog
Find the right food and portion size for your dog
Recurring skin, paw or ear problems are often related to feeding that is not optimally balanced.
