Can dogs catch lice and if so, how can it be prevented or treated?

Yes, dogs can catch lice, but it is not very common. Lice infestations in dogs can be prevented by maintaining good hygiene and avoiding contact with infected animals. If a dog does get lice, it can be treated with special shampoos or medications prescribed by a veterinarian. Regular grooming and cleaning of the dog's environment can also help prevent lice infestations.
