I noticed a Tiny black tick on my chihuahua so I had my husband take it off and its been a week now and there is a red bump! What should I do is this normal? Does it mean that she has lime disease??? My other dog had a huge tick on her and I had to shave her to check her for anymore but she didn’t and now where the tick was is fine no bumps or anything and this is why I am so scared about my chihuahua! Please help!
