We recently introduced max (not about 13 weeks) to millie (1 year) and millie was an absolutely darling with him. After a few hours she just started to ignore him and wasnt too bothered about the new intruder. However, he is DESPERATE for her to be his playfriend and when he clocks her he follows her around jumping on her constantly. Shes very placcid and will not defend herself, she just moans and growls as he gets her in a headlock or launches himself from above at her! When hes doing nothing not bothering her she is fine, but shes started to get edgy and walk around grumbling when hes around. The other day i reached out to reassure and she went for me too. Max has his own room at the moment while he is so little mainly to keep him from the dangers of the house when we are at work, so millie gets peace and quiet in the day, but im relucatant to let him stay out in the daytime incase he really stresses her out. Im also hoping as he gets older and calmer he will stop being so domineering over her! When they are just playing it is lovely as they chase each other all over the house (i watched to check if he was being aggressive, but then she chases him back in and its definately playful) i just dont want to have to keep them seperated for much longer as its not fair him being stuck in a room Any advice or similar stories?
