How a disrupted microbiome can lead to itching in dogs

What is your dog's skin microbiome

Your dog's skin microbiome or skin flora is its main line of defence against external pathogens. Think of it as an army-one with 'healthy' micro-organisms as soldiers, ranging from viruses to fungi to bacteria. By the way, and this goes for both humans and dogs, these organisms are essential for good health and are abundant on the skin, in the intestines and in the vagina.

Many factors influence the composition of the skin microbiome: 

  • lifestyle

  • diet

  • gender

  • age

  • environment

  • medication, antibiotics, shampoo and other skin or fur products

If your dog's skin microbiome is disturbed, its skin's defence system is weakened. The risk of skin allergies, eczema and inflammations increases, causing your dog to suffer from a permanent itch (1-4).

This is how you keep your dog's skin (microbiome) healthy

Wash your dog as little as possible

If you do wash him or her, use a microbiome-friendly shampoo-one especially designed for dogs. With most shampoos, your dog's skin will need seven (!) days to recover. Although antiseptic and antibacterial shampoos may be necessary in some cases, they do kill all the good soldiers in the microbiome. So only use such shampoos in consultation with your vet.

Only use antibiotics when you really have to

Antibiotics not only kill the bad bacteria, but also the good ones. So avoid them when you can.

Give your dog the right food

Poor nutrition is the cause of many skin problems. Call your vet and find out what kind of food your dog will benefit from. Supplement your dog with essential nutrients to feed the skin from the inside out. Immune & Tune is packed with these essential nutrients: vitamin B, omega-3 fatty acids (DHA & EPA) and Zinc.
