Finding the right balance for bath time can feel like a bit of a balancing act. While we all love a fresh-smelling pup, washing your dog too frequently can actually do more harm than good by stripping away the natural oils that keep their skin healthy. On the flip side, leaving it too long can lead to a build-up of dirt and a less-than-pleasant "doggy" aroma in the house. Every dog is a unique individual, and their grooming needs are influenced by everything from their breed to how much they love rolling in the mud. This guide will help you navigate these factors so you can keep your best friend clean, comfortable, and healthy.
Factors to consider for bathing frequency
There is no hard and fast rule every owner must stick to when it comes to bathing your dog however, bathing too frequently and sometimes even too little can cause health issues.
Depending on the dog, bathing can be an enjoyable time for both pet and owner and even a great opportunity to check for health issues such as the presence of any new lumps or bumps. For others, bathing can be a stressful event so there may be a preference for as little bathing as possible.
Different factors will contribute to how often you need to bathe your dog. This may include things such as:
- Coat type
- Whether your pooch is indoors or outdoors
- Allergies or other skin issues
- Level of dirt exposure (e.g. working dogs or dogs who regularly swim)
- Owner preference for smell and cleanliness
If asked, most vets would agree that unless dirty, dogs without any health issues don't require very frequent bathing. Typically it's not recommended to bathe your pooch more often than once fortnightly to once monthly. Unless there is a specific medical condition, bathing more often than this can put your pooch at risk of dry, irritated skin due to the stripping of natural oils and protective barriers of the skin.
Activity level and your dog's routine
- Dogs with high activity, frequently outdoors, or engaging in messy activities: Tend to accumulate more dirt, mud, or debris in their coats. They may benefit from more frequent bathing, typically every 2-3 weeks or as needed
- Less active indoor dogs or those with sensitive skin: Might only need baths every 2-3 months
Understanding different coat types
- Long haired dogs: May require bathing every month. More importantly they should be groomed daily with an appropriate brush for their coat type to prevent matting
- Short haired dogs: May get away with a good groom with a brush such a Kong Zoomgroom and freshen up with some doggy bath wipes
- Hairless dogs: Dog breeds such as the Chinese crested and Xoloitzcuintli do benefit from weekly bathing to keep their skin in top condition. After bathing they also require the application of a moisturising lotion
- Breeds prone to oily skin: such as West highland white terriers may need to be washed with an anti-seborrheic (anti-grease) shampoo such as Mediderm weekly to minimise oil build up and odour

Managing allergies and skin issues
- Some dogs suffer from allergies or other skin conditions so may need regular bathing with a medicated shampoo like Malaseb or gentle oatmeal shampoo to help manage the condition. The frequency of bathing in these cases should be set out by the pet's veterinarian
- Make sure to follow shampoos with a moisturising conditioner

Flea and tick control
When using flea and tick treatments and considering bathing frequency, the primary rule depends on the type of medication used: oral treatments are unaffected by water, but topical "spot-on" treatments require a waiting period to ensure efficacy.
- It is ideal to bathe your dog before applying the treatment, ensuring their coat is completely dry first
- If you need to bathe them after application, the general recommendation is to wait at least 48 hours to allow the product to fully absorb into the skin's lipid layer
- To maintain the treatment's protection, you should use a soap-free shampoo, as standard soaps can strip away the active ingredients
- Ensure the application site remains undisturbed by keeping the dog out of the rain and preventing other pets or children from touching the area until it is completely dry

Owners health and home comfort
Regular grooming and bathing can play a part in helping to limit shedding of fur and dander (microscopic particles from saliva, skin or hair), and reduce allergies in humans. Other methods to help limit allergens include:
- Utilising products such as vacuums, air purifiers or air conditioners that contain a HEPA filter
- Washing bedding at high temperatures
- Wet mopping/dusting to trap and remove allergens
For owners who simply dislike their pooches "doggy" smell there are a range of effective dog friendly coat sprays to help keep them fresh in between baths.
Regardless of the frequency of bathing it's important to choose a dog specific shampoo. These are safe to use in comparison to human shampoos which are often not suitable and in some cases can be harmful.
Risks of over-bathing your dog
Overbathing can:
- Strip away the natural oils that protect a dog's skin, leading to dryness, irritation, itching and potential inflammation and increased susceptibility to skin infections
- Lead to a dull, brittle coat prone to tangles and breakage, impacting the hair's natural shine and texture
- Alter the dog's natural scent and compromise their skin's protective barrier
To maintain a healthy balance, it's crucial to adhere to a bathing schedule appropriate for your dog's breed, skin type, and activity level, ensuring their skin retains its natural moisture and protective oils.
When to seek expert advice
Seeking expert advice from your veterinarian, groomer or our Vet Squad about bathing your dog is advisable in several scenarios.
- If your dog has specific skin conditions such as allergies, dermatitis, or infections, to determine an appropriate bathing routine and suitable products that won't exacerbate their condition
- New dog owners unsure about the ideal bathing frequency or the use of grooming products
- Persistent skin issues, excessive shedding, or coat abnormalities post-bath
- Before introducing any new grooming products or techniques to ensure they are safe, appropriate, and beneficial for your dog's skin and coat health
