Hi we have a 12 year old lab collie cross bitch. She is very well behaved and can be timid around strangers. We have just become grandparents and our dog is behaving oddly when the baby is I the house. As soon as he is in the house she starts pacing around and panting really heavily. She will not lie down and if anybody is walking around holding the baby she is shadowing them all the time. We have resorted to putting her out in the garden but she continues with the same behaviour out there as well. Does any one have any suggestions?
