hello
i have a 2 and half years old bitch staffordshire bull terrier and a 6 months old boy. my bitch is hopefully 3 weeks pregnant the past week she has been realy snappy towards my other dog she has not been like this before with him . we got him when he was 6 weeks old and they have been fine up to now all i can think of why she has been like this is she must be pregnant . anyone can give some advice out there . thank you tracy

She may well be snappy.. You should separate them before your boy gets hurt. HTH
