Hello, and thanks for your question about Jack. If Jack has focal lesions where he's getting hair loss and red spots, this is often a sign of a skin infection. This can often occur secondary to allergies or fleas. Jack should be seen by your vet, as he may require a course of oral antibiotics to treat his skin. Hope this helps!

    It looks as though poor Copper may have some skin irritation. This can be caused by a number of reasons including fleas, allergies, or skin infections. Watch for any signs of chewing/scratching and try to deter these behaviors if possible. I would recommend having him seen by a veterinarian as he may require medication to treat this irritation. It is very difficult to determine the cause without assessing him in person.
