The two boys left this week and she does have a bit of time out - perhaps she needs more? I take her out for a long walk and then have her sit with me whilst the puppies are sleeping and I try to give her the usual amount of time and fuss as the puppies (although hard!!) She has one long and one shortish walk a day (as before pregnancy). But at times when the puppies are playing nicely she will bark and snap at them - is this just because she is tired and had enough??!
