Novice owner here of two rehomed dogs, a chi and a pug cross. Previous owners didn't walk them and I suspect they had little early socialisation. This manifests itself in the chi, particularly reacting to other dogs... Up on hind legs, snarling. She is also growly with strangers to the house, though soon comes round. Rescue aren't forthcoming with help or advice. I guess I'm just wondering how much of a problem this is going to be and whether the growliness/reaction to other dogs is likely to escalate or can be managed? I have two DDs (one of whom is 3) so just want to be clear I guess on what I'm dealing with and whether I need to be concerned?
