Choosing the Right Topical Formulation in Veterinary Dermatology: Why One Size Does Not Fit All
Dermatological disease is one of the most common reasons for veterinary consultation in dogs and cats. From allergic skin disease and secondary bacterial or yeast overgrowth to seborrhoeic disorders, interdigital disease and localised inflammatory lesions, dermatological cases can be challenging to manage, particularly when the condition is chronic or recurrent.
For many patients, topical therapy forms an important part of the management plan. However, choosing a topical product should involve more than simply selecting an appropriate active ingredient.
The formulation, application site, extent of disease, coat type, patient tolerance and, perhaps most importantly, the owner's ability and willingness to use the product at home can all influence the outcome.
A product that looks ideal on paper is unlikely to be effective in practice if the owner finds it too difficult to apply consistently.
The dermatological conditions veterinarians see most often
Canine and feline dermatology encompasses a broad range of conditions. Some of the most frequently encountered include allergic skin disease, flea allergy dermatitis, superficial bacterial infections, Malassezia overgrowth, seborrhoeic disorders, pododermatitis and inflammatory conditions affecting skin folds.
Allergic skin disease is particularly important because the primary disease can create an environment in which secondary microbial overgrowth develops. Dogs with atopic dermatitis, for example, may experience recurrent bacterial or Malassezia infections, while concurrent ectoparasites or adverse food reactions can further complicate the clinical picture. Current guidelines therefore emphasise a structured diagnostic approach, including assessment for parasites and secondary infection rather than assuming that pruritus is attributable to allergy alone.
Malassezia dermatitis is another common consideration, particularly in dogs with underlying allergic disease. Clinical signs can include erythema, pruritus, scaling, greasy skin, hyperpigmentation, lichenification and characteristic odour. The ears, skin folds, paws and other warm or moist areas may be particularly affected.
Bacterial pyoderma can similarly occur as a primary problem or, more commonly, as a secondary complication of an underlying dermatological disorder. Importantly, topical antimicrobial therapy is now strongly emphasised in the management of surface and superficial pyoderma, providing an opportunity to reduce unnecessary systemic antimicrobial use. The common theme is that there is rarely a single topical approach that is ideal for every dermatological presentation.
Shampoo, mousse, spray, cream or serum?
One of the simplest ways to improve compliance with dermatological management is to consider the formulation as carefully as the ingredients.
Shampoo: ideal for widespread disease
Shampoo remains an extremely useful option when a large proportion of the skin surface is affected. It allows the product to be distributed across extensive areas of skin and coat and, depending on the formulation, can help remove scale, excess sebum, allergens, crusting and other surface debris.
For infectious or microbial-associated disease, appropriate medicated shampoos can also provide antimicrobial treatment over large areas. For example, current canine pyoderma guidelines recommend shampoos as an appropriate formulation for widespread disease, while noting that contact time and application technique are important considerations.
However, shampoo also has a practical disadvantage: it requires time.
The dog or cat may need to be thoroughly wetted, shampooed, massaged into the coat, left for the appropriate contact time and rinsed. Drying can add another stage to the process.
For some owners this is perfectly manageable. For others, particularly those with large, long coated or anxious dogs, it can quickly become a barrier to compliance.
This is where leave-on formulations can provide an important alternative.
Mousse: practical leave-on coverage
A mousse or foam can be particularly useful when frequent bathing is impractical or when large or moderately localised areas need regular topical care.
Because it is a leave-on formulation, it removes the need for rinsing and can therefore make treatment significantly easier for owners.
Mousses can also be useful around areas such as the paws, axillae, groin and skin folds, where achieving good coverage with a shampoo may be difficult.
Current antimicrobial guidelines specifically recognise mousses and other leave-on formulations as useful options when frequent bathing is not practical and for areas such as interdigital skin.
Spray: targeted and convenient
Sprays are particularly useful when the problem is localised and the affected area can be accessed easily.
They can be useful for focal areas of irritation or superficial lesions and can offer a quick application without the need to manipulate the affected skin extensively.
For owners managing a painful or sensitive area, a spray can also be preferable to rubbing a cream directly onto the lesion.
The key advantage is targeted application with minimal preparation.
Cream: for localised areas requiring direct application
Creams are best considered when the affected area is relatively small and the product needs to remain in contact with the skin.
They can be useful for localised areas such as focal irritation, dry or compromised skin, or selected areas where a more concentrated application is appropriate.
The disadvantage is that application requires the owner to physically handle the affected area. This may be easy on the body but more challenging around the paws, interdigital spaces or painful lesions.
Serum: lightweight skin-focused care
Serums provide another option where the primary objective is targeted skin care rather than washing the entire animal.
A lightweight serum can be particularly useful for localised areas or compromised skin where a leave-on product is preferable.
For example, formulations containing ingredients selected for skin conditioning and barrier support can complement the wider management of chronic dermatological disease, where maintaining the condition of the skin is an important part of long-term care.
The importance of choosing the product around the patient — not just the diagnosis
It is tempting to think about dermatological products in terms of a simple equation:
Condition → product.
The decision is more complex:
Condition + lesion distribution + coat + skin condition + patient tolerance + owner practicality → formulation.
Two dogs with similar dermatological diagnoses may therefore require completely different approaches.
Consider a dog with widespread seborrhoeic skin and another with a small, localised lesion between the toes. A shampoo may be highly practical for the first patient but unnecessarily difficult for the second.
Similarly, a dog with recurrent interdigital disease may benefit from a leave-on formulation that can be applied regularly without requiring the owner to bathe the entire patient.
This distinction is particularly important in chronic dermatology. Treatment plans can involve weeks or months of ongoing management, and therefore compliance becomes a clinical consideration in its own right.
The most technically sophisticated product is of limited value if the owner cannot realistically use it at the recommended frequency.
Don't forget the difficult-to-reach areas
The paws are an excellent example of why application technique matters.
Interdigital spaces, nail folds and the skin around the pads can be difficult to access, particularly in dogs with dense hair or conformationally tight interdigital spaces. These areas can also remain warm and moist, creating an environment in which microbial overgrowth may occur.
A conventional application may therefore result in product being distributed over the top of the paw while failing to adequately reach the interdigital spaces.
This is where a dedicated application tool can make a surprisingly significant difference.
A small brush designed specifically for the paws, nail folds and interdigital spaces can help owners physically reach areas that are otherwise difficult to treat. It also provides a more targeted approach than attempting to apply a product with a large sponge or simply pouring shampoo over the area.
The goal is not to add another unnecessary product to the treatment plan. Rather, it is to make the recommended topical care more achievable and more precise.
A new dermatology option for UK practices
This approach to dermatology is one of the reasons the launch of Maxani Animal Healthcare in the UK is particularly interesting.
Rather than offering a single formulation and expecting it to fit every dermatological situation, the Maxani range provides several different routes of topical application, including shampoo, mousse, spray, cream, serum and a dedicated brush for difficult-to-reach areas.
The range includes products such as PyoMax, designed around cleansing and care of skin prone to microbial imbalance; AtopOat, focused on the care of sensitive and allergy-prone skin; and Skin Repair Serum, providing targeted leave-on skin care.
Other formulations within the range, including SeboSilk Shampoo, KeraSooth Cream, Regular Mousse and Honey-O3 Gel, provide different approaches to skin and coat care depending on the patient's presentation and the practical requirements of the owner.
One of the strengths of the range is therefore not simply the number of products available, but the variety of formulations and application methods.
A veterinary professional can consider whether the patient is likely to benefit most from a whole-body wash, a leave-on mousse, targeted spray application, a localised cream or serum — and whether a dedicated application tool could improve access to difficult areas.
Ingredient selection still matters
Formulation alone is not enough.
The ingredients need to be appropriate for the intended use, and the veterinary professional should consider the condition of the skin before recommending any topical product.
Compromised skin may be more sensitive to potentially irritating ingredients, while excessively degreasing products may be inappropriate for some patients. Conversely, patients with greasy seborrhoeic skin or significant surface debris may require a different approach.
The Maxani range incorporates ingredients selected for different aspects of dermatological care, including ingredients such as oat extracts, allantoin, panthenol, hyaluronic acid, squalane and selected lipid components, depending on the product.
The important point is that the ingredient list should always be considered in the context of the patient, the skin barrier and the intended purpose of the product.
The owner is part of the treatment plan
Perhaps the most overlooked aspect of topical dermatology is that treatment does not finish when the patient leaves the consultation room.
The owner must implement the plan.
If the recommendation involves bathing twice weekly for several weeks, will the owner realistically be able to do this?
If the affected area is the interdigital skin, can they reach it?
If the patient dislikes bathing, would a leave-on mousse be more practical?
If the disease is localised, is there a reason to expose the whole coat to a shampoo when a targeted formulation could be used instead?
These questions are not merely about convenience. They can directly influence adherence and therefore the success of the management plan.
Good dermatological care is therefore not only about selecting the right ingredient. It is about selecting the right formulation, for the right patient, in the right location, in a way the owner can realistically maintain.
Conclusion
Veterinary dermatology rarely has a one-size-fits-all solution.
The same diagnosis can present very differently between patients, and the most appropriate topical formulation can change depending on the distribution and severity of lesions, coat type, skin condition, patient tolerance and owner circumstances.
For this reason, having access to different formulations can make dermatological management considerably more flexible.
The arrival of Maxani Animal Healthcare to the UK provides veterinary teams with a broad dermatology-focused range encompassing shampoo, mousse, spray, cream, serum and targeted application tools. Combined with carefully selected ingredients for different skin-care requirements, this allows the formulation to be considered alongside the clinical presentation rather than as an afterthought.
Ultimately, the best topical product is not necessarily the one with the longest ingredient list or the most sophisticated formulation.
It is the product that is appropriate for the skin, appropriate for the application site, appropriate for the patient — and practical enough that the owner will use it.
