We have a 13 year old Maltese poodle mix and adopted a new puppy in January that is now almost 6 months old. They like to fight a lot but I can’t tell if they’re just playing. The puppy is very obviously just playing because she’s wagging her tail and booping my older dog then running away and coming back to boop her again and things like that, but my older dog acts like she’s trying to eat the puppy up. (Which is an interesting thing to see considering old lady is 10 pounds and puppy is probably close to 30 now) she looks so angry she’s barking and jumping at the puppy and biting at her. She doesn’t usually actually bite her unless she just nips at her ear, but I always separate them when they start fighting. But my older dog is sneezing while she fights so I’m not sure if she’s playing or not. So my question is, does sneezing always mean they’re just playing? Because if they’re just playing I don’t want to separate them every time, just watch them closely and make sure they don’t get too rough for my old lady because I want my old lady to bond and get more comfortable with the puppy.
