Allergies, as you know, affect not only humans but also our dogs. However, attempting to treat one problem at home without professional advice can cause further issues for your dog. That, for one, is human allergy eye drops. Do not use eye drops meant for humans on dogs. These drops have been tested and developed for the human eye, not a dog’s eye. However, the good news is there are dog eye drops out there to treat dog allergies.

Why You Should Not Use Human Drops on Dogs

  • It could contain toxic ingredients.
  • Can be treating the wrong problem without a proper diagnosis from a vet, which can make the problem worse

Available eye drops for dogs are either unmedicated for more of a soothing approach or medicated, meaning they have healing powers like antibiotics and anti-inflammatory.

The unmedicated dog eye drops work for very mild eye problems. See here my dog with allergies and his journey through his eye issues.

I used unmedicated allergy eye drops for dogs. They’re designed to help relieve the symptoms of irritated, dry and sore eyes in dogs. You can either drop them in if your dog lets you, or you can put a bit on a cotton pad and gently rub the solution over the eye area. Alcohol-free and has no harmful ingredients to dogs.

Eyes are very important and can quickly change; a week later, after getting better, his eyes escalated, so if your dog’s eyes look like this, you must take them to the vet. As unmedicated drops will do nothing for them, your dog will need proper consultation from a professional and will likely be prescribed medicated eye drops.

EYES – allergic conjunctivitis

Symptoms of eye issues in dogs often include:

  • Bulging eye
  • Cloudy blue eye
  • Discharge, green, yellow, clear
  • Watery eyes
  • Excessive blinking
  • Eyelid swelling
  • Pawing at the eye
  • Redness
  • Light sensitivity
  • Squinting

The eyes are a very delicate area for dogs. Not only do they need them to see, but they will also cause a lot of pain and discomfort if left untreated. 

It would be best to take your dog to the vet for any symptoms such as bulging eyes, green or yellow discharge, swelling and cloudy blue eyes, or anything that you think needs attention. After all, you know your dog; if their eyes don’t look right, a vet needs to see them immediately.

Pawing at the eye

Another possible onwards issue from allergies is that a dog can paw at the eye area of a mildly irritated eye, thus causing them to scratch the surface. See here my dog’s left eye, which the vet diagnosed as minor scarring from scratching. You can also notice a little blue tinge from scratch pressure build-up.

Pawing at the eye has caused a scratch line, as per the image below, diagnosed by the vet.

Potentially serious common eye issues in dogs

  • Conjunctivitis
  • Ulcers (usually seen in older dogs)
  • Foreign objects getting trapped, such as shrubbery and depbery
  • Inverted eyelashes

Medicated Eye Drops For Dogs

Medicated eye drops are given to dogs to treat eye issues and conditions. Such as conjunctivitis, which can only be prescribed by a veterinarian professional and given after consultation or purchased online with a prescription given to you by a vet that you will need to upload to show proof before purchase.

These can include the below eye drops for dogs:

  • Chloramphenicol
  • Ciprofloxacin
  • Clorogen
  • Exocin
  • Isathal
  • Remend

Isathal drops are what I was given for my dog after a trip to the vet. It worked very well. The only issue I had is he didn’t like me putting them in. However, I gave him plenty of boiled chicken treats which helped me administer the drops.

Unmedicated Eye Drops

Unmedicated drops are the perfect solution for any dog with sore, dry or irritated eyes. They can also help clear up foreign surface particles in the eyes and relieve discomfort. However, treatment-wise, these are just eye soothers. 

You now understand that you shouldn’t use human eye drops on dogs, and you must use eye drops designed for dogs for the mild irritations that affect your dog’s eyes. Remember that the eyes are essential to your dog. You should always take your dog to a veterinarian professional for any severe or unknown eye conditions to get a proper diagnosis or medicated eye drops. The vet has not only been trained in eye health, but they have seen and treated many dogs with many eye problems, and they will be able to help your dog a lot better than yourself trying to guess and diagnose eye problems at home. 

However, one thing that a vet will most likely not suggest to you is to improve your dog’s immune system to handle allergies better through nutrition.

So what you can do instead is help your dog’s immune system so that it can cope with allergen threats through food. It will give your dog the best fighting chance. 

First, let’s learn a little about allergies in dogs.


Many dogs are affected by allergies because they are constantly exposed to allergens. Allergens can severely affect a dog’s immune system and health.

The immune system will usually function perfectly when the dog is healthy. Occasional harmful allergens, viruses or bacteria entering the body will be met by firm and capable secondary immunity cells and often eradicated quickly.

However, when the immune system deals with such issues as allergies daily, it becomes tired and overworked. If the immune system is tired when it meets these cells that bring severe allergies into the body, it is less likely to be able to cope.

Add to allergies a poor food source with low vitamin and mineral content, and the immune system has a lot to deal with. Therefore, allergies often lead to severe illnesses when dogs are also fed poor-quality food.

Allergy Causes In Dogs That Effect The Eyes:

  • Cleaning Products
  • Dust
  • Mould
  • Parasites
  • Perfume
  • Plants
  • Plug-in Air fresheners
  • Pollen
  • Scented Candles
  • Secondhand smoke

How You Can Help A Dog With Allergies Through Nutrition

When a dog has allergies, every day, the dog’s immune system works extra hard to help fight the threat. Whilst working hard on fighting allergies, it can use up all the resources in that area, leaving roles that the immune system also does in jeopardy. Such as cell renewal or fighting severe illnesses like cancer.

So as a dog owner that’s willing to help your dog keep up with the allergy threat and to be able to manage it with a solid, robust immune system, you can and should provide your dog with the very best nutritional foods. 

You may think you are already giving your dog the best and healthiest commercial dog food, but you might not. 

Firstly check the back of your dog food packet. Ignore the front marketing because every commercial dog food out there is the best formula in the world if we just read the front packaging. 

If you find ingredients like bone meal or meat derivatives, big long words that you can hardly pronounce, and the percentage of carbs is high, then the dog food you’re giving your dog isn’t the best and isn’t offering your dog the best nutritional value to fight allergies.

If you have found these ingredients, you have a few things that you can do to improve your dog’s food nutritional intake.

Four Options To Nutritional Improve Your Dogs Food

  1. Choose a different type of food altogether, such as raw or homemade
  2. Choose a better quality commercial dog food 
  3. Add fresh food toppers to present food
  4. Give your dog a good quality multivitamin tablet alongside their food

Change To A Raw Diet For A Food Nutritional Boost

The idea of raw food is that it’s as close to a dog’s natural diet in the wild. Raw food is very nutritional; however, it’s not for everyone’s taste.

Mine and My Dogs Opinions On Raw Food

Even though I am not eating it myself, I found it smelt a bit pondy, and not only that, my dog wasn’t keen on it. Handling raw meat and storing it was a minor concern, ensuring I washed the utensils and hands and that the bowl wouldn’t be left out with any food that could attract flies. However, nutritionally it certainly outweighs my opinions. 

He smelt it and walked off. I’m sure he would have eaten it if he were hungry enough.

If you can put up with the smell, you are careful with the raw food, and your dog loves it. It is very nutritional and great for dogs with allergies since it will give them the best quality ingredients and a robust immune system ready to tackle anything!

It’s all about what best works for you and your dog. There is no right or wrong answer when deciding to feed raw food to your dog.

Homemade Food Option For Ulitmate Controlled Nutrition

Homemade food is the ultimate nutrition for your dog. It will contain fresh, suitable, no preservatives, chemicals or fillers, only the finest quality ingredients! That you can control.

However, making homemade meals for your dog can be very time-consuming.

It is reasonably simple to do. The best way to do it is to offer your dog an excellent variety of lean meats, organ meats, fruit and vegetables, rice, and oats over a two-week period. Then, your dog should get all the nutritional value that they need. 

Be aware that one nutrient often overlooked when dog parents start cooking for their dog at home is calcium. In the wild, dogs would have crunched down on bones daily. So, it is recommended to include a calcium powder sprinkled over the food before serving.

Dogs can also get calcium from eggs, broccoli, kale, and spinach. With all these, a dog can eat safely in the correct portion sizes.

Excellent Healthy Commercial Food Ingredients Found On Back Label To Look Out For

Vegetables: Not derivatives of vegetables. The word vegetable needs to be listed on its own, and are good quality vegetables fit for human consumption, unlike derivatives.

Botanicals, Herbs or Plants: These are added health enhancements for your dog. If listed on the label, the quality is excellent, and your dog’s health is at the forefront of their company.

Pure/Fresh Meat: A highly nutritious and palatable protein source of meat taken from a specific animal. Such as beef, chicken, or duck. The better quality dog foods will have pure or fresh meat labelled.

These are the three most essential ingredients to look for when picking dog food for your dog.

Fresh Dog Food Toppers To Enhance Nutrition

Best Practises When Adding Toppers To Kibble or Wet Food

Try to stay away from carbs when adding topper food items such as pasta, potato, or rice because dogs need fewer carbs, and their food is more than likely loaded with them already.

Dog’s immune systems will benefit instead from carbs from some extra protein, fats, and vitamins like ACE or K.

Toxic Foods

When you add any toppers to your dog’s food, ensure that they are plainly cooked and that you haven’t added any seasoning. 

Some of the very toxic foods to dogs that we eat can be fatal such as:

  • Chives
  • Garlic
  • Leeks
  • Onions
  • shallot
  • Spring Onions
  • Garlic

If you want to know more about these foods, I have written a detailed article explaining what happens to dogs when they eat them, along with prevention and recovery times in case of ingestion.

Artificial Sweetener

Sweetener is a sugar substitute, and its proper name is xylitol. It’s very toxic to a dog so keep your dog well away from any foods or drinks that may contain this. Even chewing gum contains artificial sweeteners, and most foods with low calories or zero sugar usually contain xylitol. Always read the labels and check for them listed.

Wet Food And Dry Food

  • Apple without seeds
  • Boiled Broccoli
  • Boiled carrots
  • Cauliflower
  • Chopped peppers
  • Freshly boiled chicken
  • Freshly boiled turkey
  • Green Beans
  • Pieces of fresh cucumber
  • Raspberries
  • Sardines in spring water (once a week only)
  • Scramble, boiled, or poached eggs
  • Spinach raw or boiled
  • Watermelon without seeds
  • Probiotics: help a healthy digestion
  • Goats Milk: for a healthy hydration boost
  • Herbs: rosemary, sage, turmeric, parsley

Multi-Vitamins For Dogs To Enhance Their Immune System

Like dog food, even multivitamins can contain nasty ingredients aswell as low-quality ingredients, which are not even worth your dog taking and will not offer any benefit to their health.

When choosing a multivitamin, never pick the cheapest and the most mass-produced manufacturers. Always check the back of the ingredients.

For example, Zesty Paws, as below, my findings of their ingredients added to the Multivitamin Bites. I have broken each component down with an explanation so you can better understand what to look for in a good multivitamin.

  • Large Dogs: Over 75lbs = 3 Soft Chews Per Day

Human Hay Fever Tablets

Giving your dog an allergy tablet meant for humans for the first time is a bad idea. If you don’t know what they are allergic to or if the problem is related to allergies, it can cause more harm than good. It’s best not to take any chances by giving human medication without first getting consent from someone who does understand these things, like a vet. 

Final Words

My advice is never to leave the eyes of a dog. Always take them to the veterinarian. My dog certainly had a lot going on with his eyes, the quick healing then leading to more issues like conjunctivitis, allergies, a cloudy blue eye, and even scratching the eye and causing damage.

This image was taken this morning, and his eyes are back to normal. Allergy-free eyes!

My happy dog with healthy eyes doing the head tilt on the sofa
The eye is back to normal.

Good luck, and remember the importance of eye health in dogs!
