Firework season is here(boo).. I have 3 dogs, the 2 adults are fine with the banging etc. The pup(9months) has gone from crying to growling and barking her bits off at the noise. Dh has nipped to get some bachs RR. Does it work? What quantities are we talking for a 6 kilo not full grown, in 1st season, very loud lady?
