the jack russell is 7 yrs old i will be watchin her but she is very protective over the baby an example is if tia cried and no one was sitting with her dog would lie by her and tia calmed down but if she cried and i picked her up dog would growl as if she thought i was hurting tia. this has stopped for now the only time the dog goes near tia is if has to walk past her to get to where shes going or tia is asleep dog lies nr her
