1 in 3 dogs may have ticks!

As part of the big tick project, supported by MSD Animal Health in collaboration with Bristol University, veterinary surgeons in the UK examined dogs during routine consultations very carefully for the presence of ticks. The study found that 2181 out 7101 dogs (or one in three) was found to have one or more ticks present. 89% of ticks found were Ixodes ricinus.

Ticks can be involved in the transmission of many vector borne diseases, including zoonotic pathogens. Infections occur via saliva during feeding, or more rarely, after the parasite is ingested during grooming. Due to recent milder winters, there has been a continuation of tick activity resulting in the need for year round prophylactic treatment for pets.

Individual vectors may harbour more than one pathogen leading to atypical signs of a single disease. Heavy infestations of ticks removing large amounts of blood can also lead to signs of anaemia. Recently sample studies of ticks in Ireland were examined for the presence of vector borne diseases carried out by University College Dublin. Pathogens commonly identified were, Borrelia burgdorferi sensu lato, Babesia spp. and Anaplasma phagocytophilum.

Lyme disease is a common tick-transmitted disease affecting animals and humans. Ixodes ticks are recognized vectors of Borrelia burgdorferi sensu lato. Also Babesia sp. which is transmitted by tick saliva affects animals and occasionally people. Patients present with moderate to severe haemolytic anemia, fever, anorexia, depression, splenomegaly and a bounding pulse. Dogs infected usually respond to treatment with imidocarb diproprionate and supportive treatment. Blood transfusions may be life-saving in very anemic animals. Illness of varying severity due to B felis in domestic cats has mostly been reported in southern Africa. An unusual feature of B felis is its lack of response to the normal babesiacides.



Skin disease in pets

Skin disease is one of the most common reasons for dogs being taken to the vet. It has been estimated that around 25% of veterinary consultations are due to skin problems. Many skin diseases are simple to cure, and within days of treatment, a full and permanent recovery occurs. However, some skin diseases are very difficult to resolve. Some unfortunate dogs suffer from chronic skin conditions which require a lifetime of daily medication, regular shampooing and almost constant veterinary supervision.


In all cases of skin disease, to give the most effective treatment, it is important to be able to identify the precise cause of the problem. Sometimes dogs with minor symptoms may respond to a general, nonspecific treatment, but if the symptoms are more severe, it is often necessary to carry out investigations to find out the exact cause of the problem.

Unfortunately, such investigations can be complicated and expensive. Although no single item may be very costly, many visits to vet are needed, often with long term medication. A complete list of possible causes of skin disease would be several pages long, but your vet will often be able to narrow down the possibilities quite rapidly, with a combination of a good case history, a thorough physical examination and sometimes using further investigations.

In some cases (such as fleas) the cause of a skin condition may be immediately apparent to the vet. During the physical examination, distinctive symptoms may be evident (such as the presence of flea droppings) which provide an immediate diagnosis. In such cases, a one-off course of medication and a check-up a few days later may be sufficient to resolve the problem. Even if fleas are not seen, vets may recommend a thorough flea treatment (such as a long acting tablet or a spot-on vial) to be absolutely sure that they are not the cause.

In other cases, diagnosis of the cause of the problem may not be simple. The vet may decide that further investigations are needed, which may involve a wide array of tests. A skin scrape is often the first stage. Skin scrapes are examined under a microscope, and allow the identification of certain parasitic mites. Even if a mite is not seen under the microscope, the vet may recommend a series of special anti-mite washes to make sure that mites have been completely ruled out. In some cases, a skin biopsy may be needed. A small wedge of skin is excised, from one or more affected parts of the body. The sections of skin are sent to a laboratory for analysis of the tissue. The microscopic appearance of the skin cells often provides useful clues about the type of skin disease.

The vet may recommend certain restrictive lifestyle changes for your dog if an allergy is suspected. This may involve keeping your dog on brown paper for bedding, on tiled floors only, and on tarmac only for exercise. If your dog improves on the restricted regime, then one by one new substances are reintroduced to your dog’s life. The old bedding may be returned to the basket, then exercise on grass may be allowed again, then access to carpets may be reintroduced. If your dog starts to itch again at any stage, then the cause of the itchiness must be the latest item to be re-introduced.

A similar approach to the diet, using specially prepared foodstuffs, may also be suggested. It is exceptionally difficult to reach a diagnosis in some cases of skin disease, and your vet may recommend a referral to a vet with a special interest in dermatology. When the diagnosis of the cause of a skin disease has been reached, a long term treatment plan can finally be devised. The process of investigation may have been lengthy, expensive and tiresome, but hopefully the resulting effective treatment will resolve your dog’s problem and make all of the effort worthwhile.

Please ensure you discuss any of your pets ailments with your vet to get accurate advice.

Harvest mites

The creature on the consulting table had six hairy legs. It had a bulging round body which was a bright orange colour. After peering at it for a moment, I looked up from the magnifying glass and said to the owner ‘Yes – it is definitely a harvest mite’.

Harvest mites are seasonal parasites. They suddenly emerge in late July, August and September, and vets regularly find them infesting the feet of dogs and cats. The mites are correctly called Trombicula autumnalis, but most people know them by their colloquial names – Harvest mites or Red mites. Adult harvest mites have no interest in mammals – it is the larvae which cause problems. The larvae hatch out in meadows and scrubland, and they stick themselves to the underside of passing dogs, cats and wild animals. They remain on the skin for several days while they feed on the skin of their host. Unlike many parasites, they do not suck blood. Instead, their saliva digests the outer layers of the skin.

The mites most commonly attach to the underside of the feet. The skin here is very thin, sensitive and easily irritated. The symptoms of harvest mite infestation are so characteristic that many owners have made the diagnosis by the time they bring their pets to the vet.Affected dogs and cats start to lick their feet, and as the irritation worsens, they begin to chew the affected areas. This self damage causes the initially small irritated area to become a large, swollen, bright red patch of skin. Some dogs even become lame because of their painful feet. When the undersides of the feet are examined, it is often possible to see the mites with the naked eye. They have a red or orange colour, and they are no bigger than a pinhead. They tend to cluster together, and they can be seen like a sprinkling of red dust between the animal’s toes. When they are examined under magnification, their distinctive anatomy can be identified, and the diagnosis is confirmed.

There are many other causes of itchy feet, so it is always rewarding to find harvest mites. Some of the other conditions can be very difficult to treat and even impossible to cure. Problems caused by harvest mites are usually easily resolved. In a few cases, it is impossible to find the mites, even though the animal is showing classical signs of an infestation. This is because some animals are so thorough with their licking and chewing that they dislodge the mites before any treatment can be given. They should be treated for the mites anyway, to prevent further problems. The mites can cause itchiness in other parts of the body – the abdomen and the sides of the head can be affected, particularly in cats.

Infestations of Harvest Mites are treated by regular applications of insecticides. These can be applied in different ways – as shampoos, powders or sprays. Anti-flea preparations often help, and these now come as long-lasting products that can be given as sprays, spot-ons or even tablets. It’s important to choose the right product, and your vet is the best person to help you do that. Animals with Harvest Mites often need other medications, such as antibiotics and cortisone, to resolve the redness, itchiness and infection which accompany infestations. All in all, a visit to your local vet is the fastest way to completely cure your pet.

Ticks….what you need to know

Spring is here, and the Spring Rise of ticks has arrived. Ticks are tiny blood sucking

parasites, closely related to spiders. They have complicated life cycles, and are not very active for much of the year. However, in the Spring and Autumn, they have so-called ‘Rises’, when there is a sudden surge in their numbers and activity. Thousands of almost invisible tick larvae climb up on grass stems and other vegetation, and wait for a suitable animal to stroll past. They wave their legs towards any passing creatures, and ‘hitch a lift’ as the animal brushes against them. They then clamber up to a suitably succulent piece of skin, and bury their needle-like mouth parts under the surface of the skin, into a juicy blood vessel. They spend the next few weeks sucking blood, and they swell up from pin-head sized to pea sized or bigger. At this stage, they relax their grip and tumble off the animal into the undergrowth again. They go through a few repeat cycles, with moults in between, and finally, they become adult ticks and they mate. The adult females go through the same blood-sucking, swelling-up phase, but when they fall off this time, they lay hundreds of eggs before collapsing exhausted and dying. The eggs hatch into young tick larvae, and the life cycle starts again.

Ticks are fascinating creatures. They can pass on blood-borne diseases, because they suck blood from one animal and them move on to another. Such diseases are common in cattle and sheep, but less significant in dogs and cats. There is one important condition – Lyme Disease – carried by ticks, which can infect humans as well as dogs. This can cause vague signs at first, and if not diagnosed and treated, can cause serious illness in both species. This is one of the main reasons why people need to take ticks seriously, and why it’s worth preventing ticks using modern medication.

As a vet in practice, I see ticks most often when an owner comes in to me complaining of the sudden appearance of a “small tumour” on their pet. Swollen ticks can look like warts. However, close examination, using a magnifying glass if needed, reveals the tick’s tiny bristle-like legs sticking out at the base of the “tumour”.

Once you have recognised that your pet has a tick, what do you do? Ticks often irritate dogs and cats, and it’s best to remove them. My personal preferred technique is to pull them out, using a proprietary tick removing tool, called an “O’Tom Tick Remover”. Wear gloves, dispose of the tick properly (in a fire, or by squashing and putting in the bin), and wash your hands afterwards.

If the head of the tick breaks off as the tick is pulled out (and this can happen very easily if you just pull them out with your fingers), an abscess can form. This can look red and swollen at first, and can develop into a large lump later. Any such reactions should be bathed twice daily in mildly salty warm water. If they don’t settle down within a few days, you may need to visit your vet for further treatment.

If you want to protect your pet from ticks, there are various options available from your vet. For dogs, the most effective preventive method is a new tablet which just needs to be given every three months: it’s highly effective, and it also prevents fleas and some mites. Sprays and ‘spot on drops’ are also available. It’s best to talk to your vet to find out which method is most appropriate for your pet’s situation.
