Buying Guide: Choosing the Best Dog Supplement for Skin and Coat

There are many things to think about if you want to give your dog nutrients to treat their coat and skin. Below are some aspects to consider, but you should always consult your veterinarian for the best suggestions.

Supplement Form

Supplements come in many forms. There are chewy treats, chewable pills, tablets, liquids, and powders. All options are effective, so most dog parents choose the one that fits their dog’s preferences best. Some dogs will happily gobble up anything that looks like a treat, so chewable supplements may be the way to go. Yet, some dogs are picky, so that might be a situation where you’d pick a flavorless powder.

Ingredients to Look for

Omega fatty acids, fish oil, salmon oil, and biotin are the most effective ingredients in the best dog coat supplements. They can keep your dog’s coat shiny and silky and their skin healthy and hydrated. Also, they can aid in treating skin and hair conditions, such as dryness, itching, skin allergies, and hair loss.

Look for supplements made with pure, natural ingredients rather than additives and preservatives. While additives and preservatives won’t cause immediate harm to your pet, they add no benefit to the formula. If a supplement has a long list of ingredients, those items should add more benefits to the product, such as improvements to your dog’s digestion, immune system, and joints.

Ingredients to Avoid

Some dog supplements on the market have chemicals that could harm your dog’s health. Avoid purchasing supplements for your dog’s skin and coat that contain the following:

• Calcium phosphate
• Lecithin
• Cellulose
• Alginic acid
• Crospovidone
• Silica
• Sorbitol
• Fructose

Artificial flavors and sweeteners can become food for viruses and bacteria. Inorganic substances in supplements can cause additional problems, such as diarrhea and allergic reactions. Always research the ingredients listed on the package to make sure they’re safe for your dog to eat. When in doubt, ask a vet about a product’s ingredient list.

FAQs

How do you know if your dog needs skin & coat supplements?

Dogs need a wide variety of vitamins and minerals to maintain healthy skin and fur. If they experience skin irritation or hair loss, they may not be getting enough nutrients from their diet. Adding supplements with omega fatty acids to their diet can help their skin and coats look healthy again.

At what age should I give my dog supplements?

It depends on the product. Most supplements will say how old a dog should be on the label, but 12 weeks is usually the earliest to give a dog a supplement. If you think your dog might need a supplement, talk to your vet about options.

How do I get a stubborn dog to take medicine?

The easiest way to give a dog supplements is to hide them in something else. You can mix the supplement with strong-scented items like wet food or peanut butter, or you can conceal it in a pill pocket.

Can omega-3 fish oil help my dog’s dandruff?

Yes, omega-3 fatty acids can potentially help reduce your dog’s dandruff. Omega-3 fatty acids, which are found in fish oil and flaxseed oil, are known for their anti-inflammatory properties. Inflammation can contribute to skin conditions, including dandruff, and by reducing inflammation, these supplements may help improve your dog’s skin health.

What causes excessive itching in dogs?

Excessive itching in dogs can be caused by a variety of factors, including allergies to food or environmental triggers (such as pollen or fleas), dry or irritated skin, fungal or bacterial infections, and even underlying medical conditions. Identifying the underlying cause through a veterinarian’s examination is crucial to provide appropriate treatment and relief for the dog’s itching.

What shampoos are best for dogs with skin issues?

The best shampoos for dogs with skin issues are those specifically formulated to address their specific condition. For dogs with allergies or sensitive skin, hypoallergenic or oatmeal-based shampoos can be gentle and soothing. Dogs with bacterial or fungal infections may benefit from medicated shampoos prescribed by a veterinarian, while those with flea infestations should use a flea-specific shampoo. It’s essential to consult with a veterinarian to determine the right shampoo for your dog’s specific skin issue.

Final Thoughts

Giving your dog a skin and coat supplement could be the key to making them healthier and more comfortable. Your dog will suffer from less scratching and shedding, so they’ll thank you in the long run.

Hopefully, this list provided helpful information about choosing supplements for your dog’s skin and coat health. If you’re able, adding one of these supplements to your dog’s daily routine could change their life for the better.
