Five vets and six vet nurses from New Zealand are travelling to Tonga's Tongatapu in August. as part of an ongoing campaign to improve small animal welfare in the South Pacific.
The team of volunteers will be there to desex animals, provide parasite treatments, and vaccinate dogs against the parvovirus.
South Pacific Animal Welfare, or SPAW, who is organising the clinic, has been facilitating similar trips to south Pacific islands since 2010.
The organisation's executive director Karen Galvan told Tim Glasgow the clinics provide the volunteers with a valuable experience, and also give the locals the chance to learn about animal health and welfare.
People in Tonga can book their animals into the clinic through Sina at Kingdom Travel.
