HI ! in the past I used to own and breed staffies one bitch "cleo" always used to bag up with milk, I used epsom salts but didnt get her to dry up enough went to the vets who prescribed galastop within two days she dried up completely it is very good stuff but can be expensive depending on each individual vets, also used kes tablets theese are prescribed to women who have given birth and they supress milk an old terrier guy told me to go to chemist and get some they worked a treat and only cost a couple of quid, this was a few years ago and not sure if they still available, anyway hope this he
