Welfare Considerations

Welfare management treats the affected dog plus all in-contact animals simultaneously and treats the environment. The infestation is more common in puppies from multi-dog environments. Prompt treatment resolves welfare impact rapidly.

Wash bedding and treat the environment — mites survive off the host for several days
Seek veterinary guidance if human family members develop pruritic skin lesions — temporary infestation can occur
