Hello! me and my family own two shih tzus, we have mavis who is 2 year old female, and we have bud-bud who is a 7 year old male. I am wondering the best enrichment activities for my dogs, currently i use sniff walks, tug of war (playing with them) and lick mats (etc). They seem extremely happy but i can't help but wonder if they ever get bored and tired of just sleeping most of the day. I'm looking for new toys, activities or just some advice.
