I took a few pics though they didn't turn out the best but lily is suddenly getting a TON of red bumps under her fur that dry out and become bloody. When it started out as 2 I was told I didn't need to see the vet but now I'm thinking I might?! Idk what it might be it doesn't seem like fleas...they're taking daily supplements to prevent fleas and I bathe them with flea shampoo quite often and vacuum daily. What could it be? Does mange start out this way?
