Allergies and your pet

Spring has sprung! With the warmer weather, trees and plants flowering and more time spent outside comes an increase in allergies in our pets.

An allergy is an exaggerated immune response to a normally harmless substance. The most common type of allergy in dogs and cats is a contact or environmental allergy. This is where the pet is coming into contact with a substance that they are sensitive to. This might be a particular species of grass, plant, tree or insect for example. We often refer to animals who are prone to allergies as having allergic dermatitis, atopic dermatitis or atopy.


Common signs of allergies in pets include:


  1. Scratching, biting or chewing at themselves – commonly their paws, the lower part of their abdomen, under the armpits and in the groin area.
  2. Dogs may drag their tummies or bottoms along the ground to relieve irritation.
  3. Cats may groom themselves excessively.
  4. Hair loss, redness of the skin or signs of a rash.
  5. Allergic conjunctivitis which causes redness and a mucky discharge from the eyes.


With the warmer weather we also see an increase in external parasites on our dogs and cats. Fleas are a common cause of scratching in dogs and over-grooming in cats, and mites can also cause itchiness and hair loss. Even just a few flea bites can cause symptoms, and fleas can live for long periods in the environment, so it is important to keep your pets up to date with their parasite control.

There are many good quality products that provide excellent protection from fleas, ticks and mites. We recommend Simparica, Nexgard or Revolution Plus to provide good quality flea control – these products kill adult fleas quickly as well as stopping fleas from reproducing – that lasts a month. Don’t hesitate to contact the clinic if you have any questions about your parasite control regime.

If you’ve noticed any signs of allergies in your pet, it is important to bring them in to have them assessed by a veterinarian quickly, as you don’t want to leave them itchy and uncomfortable or have them do any further damage to their skin. Your vet will do a thorough health check as well as have a detailed look at their skin and any problem areas. We may perform some tests on the skin to rule out parasites or infection as a contributing factor.

Some pets may require medication to control their allergies, either for the season or on an ongoing basis. We can discuss what might suit your pet best at the time of the consultation.

Cytopoint is an injectable biological treatment administered by the vet for chronic itch due to allergies that starts to relieve itch within one day and can last for 4-8 weeks. Cytopoint works like your dog’s own immune system by targeting and neutralising one of the main proteins that send itch signals to your dog’s brain.

Apoquel (oclacitinib) is a daily tablet medication that targets the specific cytokines (messengers) that cause itch and inflammation, relieving symptoms of allergic skin disease with minimal impact on the immune system. It works quickly, effectively controlling itch within 24 hours of starting the medication.

Some pets are prone to allergies due to genetics or problems with their skin barrier function, and so will require ongoing management. Some things you can do to try and keep your pets’ skin healthy are to ensure they are up to date with an effective parasite control and feed a premium quality balanced diet. Bathing dogs fortnightly to monthly with a gentle shampoo such as Aloveen, wiping their feet when they come inside or limiting their access to certain plants and grasses in the yard may help reduce their exposure to potential allergens.

If you have any questions about allergies or you would like to book a consult to get your pet checked, please give the clinic a call on 8373 0301 and let us help your pets be itch-free this spring!

    My 5 y.o. dog just had her first health scare with some tumours, and Lynbrook Vet helped us through the testing and removal process so kindly.They laid out all our options and were transparent about probable outcomes, minimising costs where … More they could.They checked-in with me throughout her surgery day with phone calls, texts and photos (non-surgical!) and patiently answered all of my questions at pick-up.I have taken my dog to Lynbrook Vet since adopting her 3 years ago, and continue to go there after moving further away because they are so wonderful.The staff in reception are always friendly and helpful and happily assist with all of our needs.It's nice to attend a clinic with a great culture, where the animals, and their humans' peace of mind, are their top priorities.

    I could not recommend both Lynbrook Vet and their sister vet Berwick/Clyde Vet any more. It is the best vet you will ever experience. We were desperate to find a vet to look after out little boy (he's a ragdoll cat who stopped eating … More and is also dealing with CKD) after being unhappy with our previous vet. We were recommended by our local community to take him to Jess who is working now full time at Berwick/Clyde Vet which has recently opened and her care (along with all the other nurses there), love, how switched on they are was one of the greatest experiences we've ever had. We thought that maybe something bad had gone wrong with his kidneys, but it was immediately picked up that one of his tooth was infected which explains the no eating (this wasn't picked up by the previous vet). Our little boy had to stay over night with a drip before going under and having 4 teeth removed. He's about to be 13 so this was a stressful situation with him going under. We were sent frequent updates with photos in the morning, during the day and just before we picked him up. They called me right before the procedure, during the procedure and right after to confirm everything was okay and if there were any updates. They knew exactly what to do and how to best keep him safe during this procedure. When we picked him up we were taken through all his blood work, x-rays and documents in elaborate detail so that we understood what everything meant and what was going on. They have even put us on a 6 month plan to get him to be as happy and as healthy as he can be when we return a week later for a free dental check up to see how his mouth is healing. We were given an aftercare plan. Pain medication that they had already been pre made!! I got a Toutube link texted to me that explains what exactly happened during the procedure. We were also given a tooth fairy certificate!!! (this vet is so extra I can't deal). This vet goes above and beyond, we saw a HUGE improvement the following day (he is SO MUCH HAPPIER) it felt like our little angel was at daycare and I could not recommend going to this vet enough! THANK YOU so much. We are eternally grateful for looking after Oscar so thoroughly.

    1000% recommend!!!! This is such a stunning vet, everyone is so friendly and forthcoming, we have been seeing them for the past 4 months with our little staffy boy Stitch! He loves it there as everyone loves him and gives him all the attention … More he needs, we have had nothing but incredible service from all the staff there. Stitch went in today for a procedure and we felt so happy and safe leaving our boy there, everyone cares for your pet, like they are family. It’s truly the best experience we have ever had with a vet.It’s a definite must, as when your little ones aren’t feeling the best they make you feel better because they keep you in the loop every step of the way!We also did puppy pre-school through them which is incredible as well as he now associates the vet with such a happy feeling we never have him worried about the vet visit… and besides that all the love and care he gets when he walks through the Lynbrook vet doors!Truely amazing
