Protecting your pets against fleas and worms

A question I often get asked by family and friends is what heartworm, intestinal worming and flea prevention products are the best for their pet? Choosing which products to protect your pet with can be a difficult task when there are so many on the market to choose from. I also understand how hard it can be to keep track of what they cover! We have written this blog to make it easier to safeguard your pet.

Firstly, it is recommended to protect against all 3 of these categories of parasites.

Heartworm is carried by mosquitos from animal to animal and results in large worms invading the blood vessels and heart. Heartworm is not usually detected as a problem in an animal until it is causing severe life-threatening illness. Treatment for heartworm disease is also very expensive but preventing it is much cheaper and easy to do.

Intestinal worms come in 4 varieties in pets; tapeworms, whipworms, roundworms and hookworms. These worms can make both pets and humans unwell. In pets they can cause weight loss, vomiting, diarrhoea and blood loss. Intestinal worms can also affect people, particularly children. They can burrow under the skin causing dermatitis, invade the eyes causing inflammation and blindness and invade the liver causing fever and inflammation. It is also important to note that worming your pet is the only way to stop people becoming infected with these worms. Human worming products do not treat these worms.

Fleas and ticks are nasty critters that bite both you and your pet. They are also very good at hiding so even if you cannot or have never seen fleas on your pet it does not mean that there are not fleas around. There are 4 life cycle stages of fleas, of which, the adult fleas that you see on your pet only form 5%. Also, some animals are hypersensitive to fleas and even one flea can cause significant irritation.

So how do I protect my pet from all of this without missing anything important? A few examples of treatment options that cover heartworm, fleas and intestinal worms are given below. Some of these products also provide additional benefits like protection against mites, lice and ticks. For people living in or travelling into tick prone areas please discuss with your veterinarian the best option to protect your pets against this additionally.


Please note that this list is by no means exhaustive as new products are introduced all the time. Please contact your veterinarian to help determine the best combination for your pet.

    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
