Map of tick risk

The risks are increased if you or your pet walk in grassy or heathland areas, and/or areas where wildlife roams.

Keep in mind that even if you live in a low-risk area, your pet might be at risk if you walk in areas with tall grass and lots of wildlife.

Lyme disease

Wild animals, especially small rodents and deer are naturally carriers of Lyme bacteria. When a tick feeds on infected wildlife the tick picks up the bacteria, then Lyme disease is spread to dogs and cats through the bite of an infected tick.

Common symptoms include:

• Fever
• Loss of appetite
• Reduced energy
• Lameness (can be shifting, intermittent and recurring)
• Stiffness, discomfort, or pain
• Swelling of joints

Lyme disease can also affect humans if bitten by an infected tick. It can vary from no illness to severe disease, and signs may start 1 to 2 weeks after infection (the tick bite).

A small red lump may develop at the site of the bite – this may then slowly spread into a large circular ‘bull’s-eye’ type rash.

Other common symptoms include:

• Fever
• Body aches
• Stiff neck
• Headache
