Dog Veterinarian: Dr. Kara, Veterinarian replied 8 months ago

I am sorry to hear that your fellow Rocky is miserably itchy.

He may have more than one allergy given how symptomatic he is now. Dogs that have one allergy often develop several with time. The effect of multiple allergies aren't additive, they actually compound one another.

Even if you don't see fleas I do recommend using protection. Flea bite allergy is the most common allergen, they are at teir highest numbers now and looking to move indoors, and it only takes one bite a month to make an allergic dog scratch so I recommend using flea prevention even if you never see one again. Frontline Plus, Advantage II or Advantix are excellent as is the new Seresto Flea collar. I don't normally recommend flea collars, but this one really works and lasts for at least 6-8 months. New prescription products on the market such as Bravecto or Nexgard, which tend to have less flea population resistance because they are new, may be worth trying too. Don’t use over the counter products, especially Hartz or Sargents, as most are ineffective if not toxic. Unfortunately even after the fleas are gone the allergic reaction can continue for weeks and I will discuss controlling that reaction below.

Other allergens can be inhaled (like grass pollen, dust mites or molds).

You can use a combination of antihistamines and high doses of omega-3 fatty acids to help with the symptoms of flea allergy and inhaled allergens. In combination fatty acids and antihistamines work synergistically, much better than either one alone. If his symptoms worsen seasonally I would think that inhaled allergens are a part of his problem. In the future I recommend starting an antihistamine about a week before he normally starts symptoms, as they seem to work better if they are in his system before the allergic cascade gets started and he gets itchy.

You can try:

1)Benadryl (diphenhydramine only don't use the combination products with acetaminophen or decongestants as they can be toxic for dogs) at 1mg to 2mg per pound of body weight or one 25mg capsule per 15 to 25 pounds of body weight orally every 8 hours.

OR 2)Claritin (loratidine) at 5mg per 25 pounds of body weight once or twice daily.

OR 3)Hydroxyzine at 1mg per pound of body weight orally every 8 hours.

OR 4) Chlorpheniramine at 4mg to 8mg per dog once or twice daily.

OR 5) Zyrtec (Cetirizine hydrochloride) at 1/2 mg per pound of body weight orally every 24 hours. That would be one 10mg tablet per 20 pounds of body weight. Make sure it is NOT the formulation with a decongestant (such as Zyrtec-D) because dogs cannot tolerate decongestants.

Some dogs do better on one antihistamine rather than another. Give the one you pick a 3-5 day trial and if it isn't working try another. Be aware antihistamines can cause sleepiness or hyperactivity in some dogs. These side effects do wear off with repeated use.

Omega-3 fatty acids are fish oil products. 3V by DVM or Derm Caps ES are good brand name products. Use the high end of the dosing schedule for your pup's weight. I recommend a dose based upon the EPA portion (eicosapentanoic acid) of the supplement as if we do that the rest of the supplement will be properly balanced. Give him 20mg of EPA per pound of body weight per day. For example an 8 pound dog could take 160mg of EPA per day.

Cool water baths with an oatmeal shampoo or chlorhexiderm shampoo (which is antibacterial and antifungal) and a conditioner with an antihistamine may help. The water rinses off allergens and the cool temperature soothes itchy skin. Do not bathe your fellow for 2 to 3 days before or after applying flea control products or the bath will interfere with the product's efficacy.

Cortisone ointment applied to the very itchy places (as long as they aren't raw) twice daily may help as well if needed. Some sprays have alcohol which can be painful on raw skin and lead to more inflammation. I don't like oral steroids, although sometimes a short course is necessary, but a topical directed at the problem areas can be very helpful and are less likely to cause side effects.

Another option if the antihistamines and omega 3's aren't enough is a product called Atopica. It suppresses the immune system a bit so it decreases allergic symptoms but it doesn't have as many harmful side effects as systemic steroids.

Another option is a newer drug called Apoquel (generic name oclacitinib) which interferes with the allergic pathway. It works very quickly to stop the symptoms of an allergy. Most dogs are reported to be much more comfortable in a day or so.

If you are interested discuss these medications with your veterinarian as they are prescription products.

Another option if you are interested, is trying immunotherapy. Your fellow would need to be tested to determine exactly what he is allergic to, and then he is given small amounts of the allergen to build up his tolerance to it, increasing the amount of allergen in the injection incrementally so that his immune system no longer responds to it. This isn't a quick fix, it takes time to slowly build up their tolerance and as he develops new allergens things may need to be added, but it is an option.

There is a new injection out (Cytopoint) that can be given by your veterinarian that can help with allergies for 4-8 weeks. It neutralizes a key allergic pathway inflammatory protein, thus stopping the itch before it starts.

If it's been a while since his last exam parasites like cheyletiella, demodex or sarcoptes mites should be looked for by your veterinarian as well if he isn't improving as they can lead to very itchy skin.

Best of luck with your fellow.
