Vet said Mr.Ziggy has Puppy Pyoderma. I did some research and apparently it's a form of bacterial infection that stemmed from all sorts of things such as food allergy, environmental allergy, flea or tick bite and a whole lot more. The initial wound/spot on his back was a pustule (pimple) that burst and has since spread to a larger size. The vet shaved off a portion of his fur to let the skin breathe. The vet gave Canisep, an anti-bacterial natural topical ointment and said to apply it 3x a day liberally. She also prescribed Immunol, an Aryuvedic tablet to strengthen the immune system along with a mixture of virgin coconut oil, borage oil and vitamin e orally daily. The wound has dried up, dried skin came off with small amounts of fur and revealed some pink skin underneath. It doesn't appear to be infected anymore and is healing but not at the rate I was happy with. His back looks like a map of the world due to hair loss. LOL. Small bald spots can also be seen on other parts of his body.. it's in his legs, neck, trunk. Some with mild pustules, some without. I was extremely worried that this might spread further or worsen as what happened on his back so I did further research and bought Nu-Stock to try it out as I have heard tons of great reviews with it. It is also natural so I am up for it! I started with the Nu-Stock treatment last Saturday, applying the ointment anywhere I can see a bald spot or irritation. I cannot believe how quickly Mr.Ziggy's condition dramatically improved overnight. A couple of pustules dried up and the best part, I can see teeny-tiny hair roots sprouting in some of his bald spots. I am extremely happy that he is improving day by day. I will post some photos when he's awake, can't take a decent photo as of the moment. I am keeping positive that my furry baby will look like his old self in a few weeks time! Nu-stock is definitely a must have for me and will always have it on hand!!
