We live in an older home and I've recently discovered that our puppy, Sophie, has been knawing on some paint near the floor level in our bathroom. I do know that the original levels of paint do have lead in them. I've been keeping her out of the bathroom and have been watching her and she seems to be fine. Should I be concerned? What are symptoms to watch out for with lead poisoning? How much does a puppy need to ingest for their to be cause for concern? I don't think she has eaten much...I found chips on the floor and it doesn't appear that she has swallowed too much. Thanks ahead of time for input...I'm concerned, somewhat, although, as mentioned, she's acting fine.
