Writers report that rabies and canker of the ear have been known, but no evidence of these diseases was found during the present investigation. Mange is also mentioned and probably exists. The usual remedies applied in the case of dogs seem to be effective wherever used and they are usually put up in a form easy to administer.
The following quotation from a letter from Spratt's Patent, Ltd., who manufacture dog biscuits and medicines, contains a number of useful suggestions for the rancher:
"In our pamphlet on dog culture, you will find chapters on all the diseases mentioned in your letter. If foxes, also, are subject to these diseases special precautions will have to be taken. Besides being wild animals, we presume they live in artificial or natural earths, and you can readily understand that, when an animal is suffering from ophthalmia, special precautions will have to be taken.
"The same applies to mange; otherwise, all the animals will soon contract the disease.
"When the animals are from four to six weeks old, they start changing their milk for permanent teeth and bone is a useful article to give, as this helps the shedding of the milk teeth. Sometimes, of course, they are so firmly imbedded in the gums that forceps must be used, and should you find an animal's head swelling, we strongly advise you to examine the mouth and re-move the milk, especially the canine, or eye, teeth."
Dr. Alexander Ross, of Charlottetown, formerly of Alberton, P.E.I., who has given much attention to fox diseases and their treatment and has acquired a rare experience in treating foxes on the numerous ranches situated within his practising territory at Alberton, has written the following article on fox diseases and surgery for this report:
"Foxes bred in captivity are more liable to disease than those which roam the wilds. In confinement they are shut off from various foods they seek in the wild state, particularly when they are not well. They are also limited as to exercise, so their muscular tone is usually below par. They often show malformation in the bones of their limbs (rickets) which, I think, is due principally to their food being deficient in bone salts and to restricted exercise. On the whole, however, I have found, in an experience extending over fifteen years, that the colonies of foxes in Prince Edward Island are remarkably free from diseases.
