What makes dogs itchy?

What could the cause be? You have to turn into Sherlock Holmes to uncover the exact reason behind your dog’s constant scratching, with lots of factors like diet, environment, and parasites to consider.
Why is my dog constantly scratching their ear?
If your dog is scratching their ear, harvest or ear mites are a pretty good bet. These small brown lumps can be hard to spot if they’re deep in the ear canal, but larger infestations can leave brown discharge on the outer ear – a vet can use an otoscope to get a better look.Why is my dog scratching or biting its behind?

You’ve always got to be on the lookout for pesky fleas and ticks too! These uninvited guests can be a real pain for dogs so need to be removed immediately, either with over-the-counter medicine or with a trip to your local vet.
Why is my dog itchy all the time?
If you’ve ruled out parasites, it’s time to look at environmental factors, also known as canine atopy or atopic dermatitis.
Is the dog itching a certain place over and over? Or are you asking yourself ‘why do dogs scratch the carpet?’ It’s most likely a contact allergy with a certain cleaning product or even a natural substance like dust or grass.

Food allergy symptoms in dogs
If a dog is constantly scratching all over it could be related to a food allergy. Dogs are different to humans, a dog food allergy is usually to a specific protein (chicken, beef, lamb) rather than wheat or other foods. Although dairy can be a common issue for dogs too.
Finding the best dog food for allergies could significantly reduce or even stop a dog from itching all the time. Spending a little extra on quality ingredients and cutting out the fillers can make a big difference in your dogs overall health.

What supplements can I give my dog for skin allergies?

There is a wealth of dog skin itch supplements available to buy, but it can be a little overwhelming trying to choose the right one.
Ultimately, in my opinion, it is better to choose a specific dog food for food allergies that has all of the necessary ingredients rather than spending lots of time and money on various brands of additional dog supplements.
What ingredients to look for when choosing the best dog food for allergies
– Fish oils Long-chain omega-3 fatty acids from fish oil and other marine sources are well studied and show significant benefits to skin and coat health.
– Zinc A product containing zinc, omega-3 and biotin product was compared to an omega-3 & biotin product (control) in canine atopic dermatitis. 63% of dogs supplemented with the zinc product presented with less itching and a reduction of medication for 4 weeks compared to 37% of dogs receiving omega-3 & biotin alone. Canine zinc-responsive dermatosis is a well-documented skin disorder of Alaskan Malamutes and Siberian Huskies.
– Selenium increases the health of the skin, potentially reducing dandruff and dry skin. It plays an important role in hair growth. A 2006 study demonstrated that low selenium in diet reduced hair growth in adult dogs.
– Biotin Essential for keratin formation, supporting growth of hair, skin and particularly, nails which may be brittle, weak and prone to breaking.

Five top tips for dealing with dogs’ itching
- Wash your dog after any contact with pollen, salt (ie, swimming in the sea), or any other common allergens.
- Give them an oat bath to calm irritated skin when it looks inflamed.
- Use a topical treatment for flare-ups such as Isaderm from Pet Drugs Online. The gel contains betamethasone, a corticosteroid and anti-inflammatory, and fusidic acid which is an antibiotic.
- Use antihistamines in the short term to reduce itching (dogs can have some human antihistamines but always consult your vet for the right amount).
- In the long term, opt for a dog food for food allergies, like Butternut Box (Get 50% off your first box here).
