advice please, ok i know its kinda trivial but. we just today aquired a puppy lurcher x and hes had the runs twice, ive given him bob martins worming tablets then about 2/3 hours later ive just had to pull a VERY LONG worm out of his back side. i called the vets and they said he should be exerting them now. has nayone seen or dealt with this before? does anyone else use bob martins? ive never dealt with this before as all our other dogs came to us worm and flea free! x
