We have a 5 months Staffy x rescue puppy. She has been with us for about two months and a half. She was scared of many things at the beginning (leaving the house, other dogs, the car) but with time and slow exposure she got much better. She is good in the house and can stay alone for a few hours without showing distress. However she is still quite timid and often has her tail tucked in between her legs which makes her look miserable and I often wonder if she is happy. She tucks her tail when she eats (unless the eating is within a play session, e.g., I hide kibble in the garden and she has to find it), every time she in the kitchen and we are cooking (she is food obsessed), when we get to new places and often in other occasions. Our house gets really cold and I wonder if that makes it worse (I am planning to get her a jumper). She sometimes pees when new people come into the house and when passing next to our cat in the garden. The cat and her most of the time do their own things but the cat would slap at her if she gets too close. She wags the tail at him and I think she would like to play, but he has no intention. My question is: why does she tuck her tail so much and what can we do to make her more comfortable? I just worry she is not happy ! I have never punished her for peeing of course and in general we try to use positive reinforcements with everything. It does happen that we get frustrated at times but we try to control our reactions because otherwise with frustration she just stops listening altogether, so that doesn't help anyone. And what can I do with the cat, is the submissive pee a normal behaviour? I hope that doesn't mean she is scared of him, but she sometimes would not go pass him if he is blocking the passage. She would not pee in the house with him but only if we are in the garden and usually we are playing and the cat hangs around. Thanks in advance!
