Signing the contract which says that no warranty has been given might be thought to be determinative if the parol evidence rule is strictly applied. However, it is subject to a number of exceptions. For instance, here there may be a collateral contract. Yet it is unclear whether the guarantee has become a term. The test is clearly objective, but it is surely relevant that Phoebe is not in the business of selling greyhounds (cf Oscar Chess Ltd v Williams  1 WLR 370). If it is a representation, then there may be a claim for misrepresentation (see Chapter 16, noting in particular the potential relevance of section 3 of the Misrepresentation Act 1967).
