The yeast-like cells of Malassezia, measuring between 1.5–4.5 μm by 3–7 μm, are characterised as phialides featuring tiny collarettes (a small, collar-like flange or lip at the mouth of a phialide from which spores or conidia are produced and released). These collarettes are challenging to identify using standard light microscopes.
The weakening of the skin's protective layers forms an environment susceptible to microbial infiltration, which could lead to severe complications. Intervening within an earlier time frame and targeted management strategies are essential to minimize further adverse effects. [10] Another autoimmune skin disease which can occur in dogs is vitiligo.
Dogs are susceptible to allergies much like their human companions. Most allergies occur in dogs over 6 months old. A dog that is repeatedly exposed to a particular allergen becomes sensitized to it, and the immune system overreacts to a subsequent exposure, most commonly manifesting in the form of skin irritation.

[1] characterised by an inflammatory response against the dog's sebaceous glands (glands found in the hair follicles in the skin dermis), which can lead to the destruction of the gland.
Dog treats are often given to pets as a reward or just to let them chew on a bone, which works their jaw muscles and helps keep their teeth clean. [67] Although dog treats carry high benefits for dogs' teeth, they can also be a source of problems like obesity when given excessively, especially human table scraps.
