This is probably a really daft question, so i am posting it here where noone can see my face

My niece has got chicken pox, will this affect my dog if he has contact with her ? I know dogs dont actually get chicken pox but i didnt know if they would affect him in any way. My niece has a massive love of merlin and if you arnt watching or not quick enough she will share things like food with him. Merlin also has a strange affinity with dummies since we brought him home last year and my niece gave him hers when he was tiny, which he actually sucked. Would it by wise to keep them seperate? My sister phoned and asked if i could take him out to cher her up as she is feeling sorry for herself.
