Instructions:
Frequency:
Apply twice daily for the first few days, then reduce to once daily and adjust as needed.
Note: If your pet has areas of broken skin or hot spots, we recommend LUCAA+ Pet Probiotic Dermo Care. This spray has a higher concentration of probiotics to support healthy wound healing.
Veterinary Recommendation for Using LUCAA+ Pet Allergen-Free Spray:
“Regarding application, I use your guidelines but would add that priority should go to contact and hairless areas of the dog’s body; so paws, tummy, groin, armpits and ears (hairless area often exposed to environmental allergens) and any skin folds that a specific patient may have e.g. around the vulva or on the face as with most brachycephalic breeds.
As a rule of thumb, we say two applications per day for the first few days then reduce to one, then reduce to ‘as needed’.
How much to spray on each time is again dependent on the severity of the condition (and size of the dog). There is about 200 sprays from each 300ml bottle so there is no need for the owner to hold back (and no negative effect from the sprays).
So, 4-5 sprays on each side of a lab size animal would result in 2 applications per day for, say, 4 days (80 sprays); followed by 1 application per day for 4 days (40 sprays); leaving a third of the container left for ‘as required’ applications.” Dr. Richard Doyle, Wylie Vets, Brentwood.

As both a stockist and a happy user myself, I can’t speak highly enough of the Lucaa+ Allergen Free Spray. It’s gentle, effective and consistently loved by my customers. The feedback I get is always the same calmer skin, less itching and noticeably happier dogs. Even hear the dog smells so much better too! It’s become a staple in my own home too. With four dogs including a Westie, a breed notorious for skin issues yet doesn’t have any! It’s simple to use, safe, and it genuinely makes a difference. A beautifully reliable product I’m proud to recommend.

I like the concept of probiotics and applying them via skin/fur seems a very clever idea. I have a CKD cat and needed a grooming product to assist with her deep undercoat which causes hairball blockages. The spray is very quiet and I apply via a slicker brush. There has been a very rapid improvement to texture and appearance, lovely to see her topcoat changing from 'cracked' to 'fluffy'. We both find the aloe fragrance challenging and hope a fragrance-free version becomes available in the future. But overall this is a good product with positive results and I hope the probiotics are busy doing their thing in the background

Our Cavapoo is struggling with seasonal allergies and this spray has become a life saver as our dog does not respond well to any conventional allergy medications. This spray soothes the itch immediately, and our dog does not seem to be having any symptoms of allergies throughout the day after spraying him in the morning. Strongly recommend this product!

My adopted Galga arrived with a dreadful yeast infection in both ears and on all 4 paws. I refused to put her on Apoquel to help with the itching as suggested by my vet so all sorts of lotions and potions along with ear drops and cleaners were prescribed. Nothing worked. What did eventually work - and with bells and whistles on - were 2 of your fabulous products: The Allergen Free Spray and the Ear Care spray! Both took a little while to get to work but, once they did, they cleared the infections entirely, never to return. I am still spraying her bedding with Allergen Free because it transpired that she also suffers from a grass contact allergy and the spray helps to keep it in check alongside a natural antihistamine product. I will never be without a bottle of both products, they are just fantastic.

I was recommended to use this spay by my pet nuititionist.I have a border terrier,Bella who is struggling with itchy skin due to yeast. we also use the shampoo along with the spray . I feel it's too early to make a true comment on the products because we are also working on Bella's diet to try and eliminate the yeast.What I can say is Bella has had no nasty reactions .I have faith in the products because they have been highly recommended to me. Do give time I'm sure they will work .

My dog has severe environmental allergies. Mites and moulds after allergy testing, high scoring on dust mites. Lucaa Allergy Spray has greatly reduced the amount of times a year his reaction is bad. His paws are the worst affected. We Spray this on him daily after wiping/washing him after walks (he wears outdoor boots too) and initially sprayed ANYWHERE he sat or slept each day for a couple of weeks, but now do this once a week. I have recommended this product to many people!
Jilly C. 5/5 Verified
Used this product daily on my dog after her walks throughout the last summer. I do believe it kept the dander and pollen levels on her coat to a minimum and she seemed more comfortable after her spray over. Her itches are extreme so it takes a whole combination of approaches to help her.
Michael P. 5/5 Verified
I am so pleased with the results that these products (LUCAA+ Ear Care and Allergen-Free) will be recommended to others.They should be utilised in the veterinary world to save antibiotics and other drugs being used.

I got the Allergy Spray and Probiotic Shampoo for my little Bichon. He'd had a terrible problem itching, having to wear a plastic cone any time I wasn't watching him to prevent him from creating wounds from scratching. I couldn't work out why he was itching. My holistic vet suggested the probiotic shampoo and I decided to also get the allergy and room sprays. His coat felt lovely after using the shampoo and his itching reduced. Using the spray regularly the itching went away completely. I think it is an environmental allergy to grass or some such, and the allergy spray completely deals with it. Very happy with the result as it is natural so is good for my dog and relieves him from the terrible state he was in.

This is the BEST spray! As someone who suffers with allergies and has an allergy prone dog, this spray has been my saving grace. The spray has helped reduce my dog’s itching and it also helps to keep my flare ups at bay. The added bonus is that you can also use it on soft furnishings and it has a lovely yet natural scent.

We're a big fan of the allergy spray and it keeps our boys coat nice and shiny. He often has dry skin after his hydrotherapy sessions, because of the chlorine, but after spraying his coat a couple of times a day, for a few days, it's back to normal :) we're also just going to try the odour spray and detergent. Photos are before and after. (Reviewed on Google)
Danielle M. 5/5 Verified
We've been using the allergen spray and shampoo for a while now and it does seem to help our dogs skin (less flakey/itchy, especially during summer and after his hydro sessions). We also spray his bedding and give the rooms a general spritz too. So far, so good :) we've also use the universal cleaner and floor cleaner and they too seem to do a good job. We're starting our journey, just now, with the dental and ear spray so I will update a bit further down the line with another review!

I bought this for my miniature schnauzer who has seasonal allergies. She is an assistance dog and an agility dog, so she spends lots of time outside. We needed to find a way to manage her allergies as well as her being able to do her job and activities. This spray has made such a difference in just a week! She’s gone from chewing her paws and itchy ears to not being bothered at all :)
Isabelle M. 5/5 Verified
Just started using the allergy spray and shampoo on my mini Schnauzer who suffers in the summer with incredibly itchy, dry and uncomfortable skin problems. Wow, these products are amazing. One bath and one week of sprays and its all under control. No more frantic itching and scratching. One happy dog who now smells amazing. Will definitely be buying more and will look at other products too.

It's early days, but the improvement (after using LUCAA+ Allergy-Free and Pet Shampoo) in one day is unreal. My dog was covered in spots on his back and they've looked quite sore and inflamed recently. I washed him with the shampoo and have applied the allergy spray 3 times and the difference already is night and day. Doesn't look red and inflamed anymore, spots all seem to scabbing over and healing. It's been an ongoing issue for quite a while now. I've tried absolutely everything from switching foods to adding supplements, buying special shampoos and of course vet treatment, which helped for a short while. I'm very happy to recommend a product that does what it says and is a lot safer and healthier for us and are pets.

LUCAA+ Pet Allergen-Free Spray introduces helpful probiotic bacteria onto your pet’s skin and coat – and into their living spaces too. These friendly bacteria naturally outcompete the ones that cause irritation, discomfort and odours. The result is a more balanced skin microbiome that helps manage environmental allergies and supports healthier skin, without the need for harsh chemicals or medicated treatments.
Start by giving your pet a quick brush or wipe to remove surface dirt. Shake the bottle well, then spray LUCAA+ directly onto the itchy or allergy-prone areas – like paws, tummy, armpits and groin – and gently brush it through. Apply twice a day for the first few days, then reduce to once daily or as needed. It’s also beneficial to spray their bedding, collars and other soft furnishings around the home to help reduce allergens there too.
LUCAA+ Pet Allergen-Free is safe for everyday use and specially developed for skin that’s prone to irritation – but if your pet has broken skin or ‘hot spots’, we recommend switching to LUCAA+ Dermo Care Spray. It has a higher concentration of probiotics to support recovery. If your pet is unwell or has a wound you are worried about, always check with your vet.
It can certainly help! Scratching often comes from environmental allergens (pollen, dust mite droppings) and an imbalance in your pet’s skin microbiome – and this spray helps with both. Many pet guardians tell us they see a difference within days, and sometimes the relief is immediate. But every pet is different, and it may take a little time depending on the severity and the triggers. Keep using it regularly – consistency is key.
Yes! LUCAA+ Pet Allergen-Free is safe and supportive for all animals – including cats, rabbits, horses, and other large and small animals. It’s free from harsh chemicals, vegan, PETA-certified, and vet-approved.
