I have an 18-month-old Lhasa Apso who has always been really good with other dogs and people. We just moved into a new house a few weeks ago after living with friends for 8 months whilst the house was being built. My friends have a female Lhasa Apso and the dogs got on brilliantly. My dog has been lost without his friend since we moved so I decided to get a new puppy. Same breed. We introduced them on neutral territory before bringing them home but my dog became really stressed out and kept growling at the puppy. My dog was really sick 3 weeks ago although he is over it now and doing really well. I took the puppy back to the breeder as I didn't want to cause my dog more stress after what he has been through with the illness. Was it just bad timing (new house and recovering from meningitis)? Should I try again in a few months?
