Dog Leishmaniasis: Prevention in UK Travelling Dogs

Canine leishmaniasis is endemic in Mediterranean Europe and beyond. Dogs travelling to endemic areas need preventive measures and post-travel screening.

Key Facts

Leishmania infantum is transmitted by phlebotomine sandflies in Mediterranean countries
Disease causes weight loss, skin lesions, lymphadenopathy and renal failure
CaniLeish and Letifend vaccines are available in EU countries and provide significant protection
Deltamethrin-impregnated collars reduce sandfly biting rates by over 90%
Infected dogs require lifelong treatment with allopurinol with or without miltefosine

Welfare Considerations

Leishmaniasis causes chronic progressive disease that is treatable but not curable. Dogs that acquire infection despite preventive measures face a lifetime of medication and monitoring. Clinical disease involves disfiguring skin lesions, muscle wasting, nasal bleeds and eventual organ failure. Prevention through vaccine plus repellent collar during travel to endemic regions dramatically reduces risk. Post-travel screening at 6 months detects early infection before clinical signs develop, enabling earlier treatment that preserves organ function.

What You Can Do

Vaccinate with CaniLeish or Letifend before travelling to endemic Mediterranean regions
Use a deltamethrin-impregnated collar throughout travel and for 3-4 months after return
Avoid outdoor activity at dawn and dusk when sandflies are most active
Screen your dog for Leishmania infection 6 months after returning from endemic areas
Treat with allopurinol plus miltefosine if infection is confirmed, following vet protocol
