Simba’s allergies first showed up when she was seven months old as puppy acne. It tends to show up in the beginning of spring on her chin and snout. I trained her at a young age not to scratch because she would open up the skin of each bump with her nails and they would end up getting infected. Instead she now rubs her chin on the carpet to scratchtheitchies.
First thing I did was replace her bowels with stainless steel bowel. These do not harbor germs as plastic bowls do. I make sure to clean her bowls regularly. I have anti-itch cream that I picked up at the pet store and apply it when I see the first little bump show up or see her rubbing her chin on the carpet. I believe that it’s something our homeowners association sprays on the lawns early spring, maybe a fertilizer. I give her a ball to carry around in her mouth so that she doesn’t spend as much time sniffing the grass and I wipe her snout with a wet towel as soon as we come in. This all seems to control the allergic acne pretty well. She might get a couple of bumps but nothing like when she was a puppy.
