Babesia in dogs: causes, symptoms & treatments reading-time-icon 2 min read

Do you often walk your dog through areas of long grass?

They could be at risk of Babesia – a parasite spread by ticks.

What is Babesia?

Babesia is a type of parasite that causes an infection of the red blood cells – this infection is known as Babesiosis.

Babesia comes in many forms, some of which affect dogs and some don’t. The seriousness of the infection varies depending on the form of Babesia but in extreme cases, Babesiosis can be fatal.

Causes of Babesiosis

The most common culprit for the spread of Babesia is ticks. Ticks usually reside in wild grassy areas during the summer months, and it’s at this time of year that Babesiosis is most common.

Affected dogs can pass on the infection to other dogs. Pregnant bitches may pass it on to their pups before birth, for example, or the parasite may pass from dog to dog if one bites the other.

As with most conditions, younger puppies and elderly dogs are at a greater risk.

Symptoms of Babesiosis in dogs

Symptoms may include:

  • A high fever
  • Lethargy or general weakness
  • Enlarged lumps on the skin
  • Red or orange urine
  • A yellow tinge to your dog’s skin, gums or the whites of their eyes (Jaundice)
  • Pale gums/tongue

Treatment and prevention

Once affected, it’s difficult for the Babesia parasite to be removed from the dog’s system completely. However, medication can be successful in keeping symptoms at bay.

If your dog displays any of the symptoms listed above, contact your vet as soon as possible so they can commence with treatment before the infection gets worse.

Preventing Babesia

As with many illnesses, prevention is better than cure! Make sure your dog is up-to-date with their parasite prevention treatments. If you’re venturing through areas where the grass is tall and unkempt, be sure to check your dog thoroughly for ticks – paying close attention to their legs, the underside of their belly and behind their ears.

If you spot a tick, remove it as soon as you can or contact your vet if you don’t feel comfortable doing so. The tick must be attached and feeding from your dog for a minimum of 24 hours before Babesia can spread.
