What can I wash my dog with is one of the most common questions new dog owners search, especially after a muddy walk or a roll in something they shouldn’t have. Here’s what’s actually safe to use.

Dog Shampoo Is Always The Safest Choice
- A dog’s skin has a different pH to ours, so products made for humans can dry it out or cause irritation
- Look for a shampoo labelled specifically for dogs, ideally soap free
- Aussie brands like Wahl and Fido’s are widely stocked at Petbarn and other local pet stores
- If your dog has sensitive skin, a soothing or hypoallergenic formula is worth trying first
Safe Household Alternatives In A Pinch
- Baby shampoo can work as a gentle, occasional substitute, diluted with water
- Oatmeal mixed into warm water can soothe itchy or irritated skin
- These should only be used occasionally, not as a regular replacement for dog shampoo
What To Avoid Completely
- Human shampoo, body wash, and dish soap can strip your dog’s coat of natural oils
- These products are not designed for a dog’s skin and can lead to dryness or irritation over time
- Scented or heavily fragranced products can also irritate a dog’s sensitive nose and skin
How Often You Should Actually Wash Your Dog
- Most healthy dogs do well with a bath every couple of weeks to once a month
- Dogs with oily coats, like Basset Hounds, may need more frequent washing
- Water resistant or thick coated breeds usually need less frequent bathing, with regular brushing in between
- Outdoor dogs who love the beach, mud, or a good roll in the yard will likely need more frequent baths
A Few Bath Time Basics
- Use lukewarm water and wet your dog’s body before their head
- Avoid getting water or shampoo in their eyes and ears
- Rinse thoroughly, since leftover shampoo can irritate the skin
- Towel dry well, especially in cooler months

According to Petbarn, most healthy dogs benefit from a bath on a fortnightly basis, though this varies with coat type and lifestyle. RSPCA Australia also advises that dogs should always be bathed using a shampoo made specifically for them, with frequency depending on coat type, skin, and activity level.

Frequently Asked Questions
1. What household items can I wash my dog with?
In a pinch, diluted baby shampoo or a small amount of oatmeal mixed into warm water can gently clean your dog. These should only be used occasionally, not as a regular substitute for dog shampoo.
2. What can I use in place of dog shampoo?
Baby shampoo diluted with water is the safest short term option. Cornstarch or baking soda can also work as a dry shampoo between baths to soak up oil and odour, though they won’t replace a proper wash.
3. What is safe to bathe a dog with?
A shampoo made specifically for dogs is always the safest option, since it matches your dog’s skin pH. If you’re out of dog shampoo, a diluted baby shampoo is the next safest alternative.
4. What can I use on my dog to wash them?
Stick to a proper dog shampoo where possible. Avoid human shampoo, body wash, and dish soap, as these can strip your dog’s coat of natural oils and lead to dry, irritated skin over time.
