dog snapping at 3 year old

[Mrs R]

Can anybody give me some good advice. I have recently purchased a 18mth old spaniel after having 13 years experience with spaniels. I bought her from a lady who informed me that she was excellent with her children 6 and 2 years. Since owning her she has snapped at my 3 year old numerous times. The couple of times was when my daughter was cuddling her and I thought that she was maybe a bit rough as these are warning snaps. But I have recently witnessed her snap at her when she has gone up to stroke her but each time this has been when the dog has been with another family member. I called the lady and she wont take the dog back as she said she has no time. I feel so sorry the dog as I dont want it passing from pillar to post but my duaghters safety is the most important thing. I called a dog trainer who quoted me �75 for 1 hour consultation she said it can be rectified. I think the dog is jealous of my 3 year old but other times she has come up to her and licked her. She is not spayed (which I am going to get done) and I am willing to take her to obedience classes but I just need some advice on how I can get the dog to respect my daughter.

So far so good thanks. I think it has alot to do with the dog settling in also.
