Do they have to have physical contact with the infected animal? Is there any treatment for it if they do contract it?
Unfortunately, mange in foxes is becoming more common, as they head out of the countryside and into suburbia for easy pickings in our bins (and on the back doorstep of those misguided souls who leave out food for them).
The cause of this horrific skin problem is Sarcoptes scabei canis.
We call it Sarcoptic Mange (although human doctors tend to refer to it as Scabies).
The mange mite burrows deep into the skin, leaving a trail of eggs and debris.
Intense itching results and there is no doubt affected foxes live a totally miserable existence.
Pretty soon, severe, secondary bacterial infection occurs. Infected foxes can and do spread the disease to our dogs, even without direct contact.
Isolation and treatment of infected dogs is vital and is definitely a job for your vet.
It is easy to confuse the early signs in dogs with allergic skin disease so tell your vet if scabby foxes are hanging around! If the affected fox stays in the area, you can protect your dogs by regular monthly applications of Advocate Spot on.
Happily, this will also control fleas, lungworm, roundworms and lice.
