Alaria infections can be prevented by keeping canines from scavenging or eating infected prey. Helminth parasites of the wolf Canis lupus from Latvia.

The reparatory nature of the lesions suggests that the inflammation is probably the result of direct tissue damage rather than an immune reaction targeted toward the parasitic antigens.
