I have a 8 year old mixed breed (German Shepard, St Bernard, Boxer) his only major health issue is his arthritis. I’m concerned because he never ever sleeps with me or even comes into my room. He always sleeps with my parents. The past 4 nights he’s been coming in my room pacing around for about 5 mins and then he lays down and sleeps with me.. I’m just weird about you it because for years he always slept with my parents. Is this concerning?
