I get what you’re saying but we only see snippets of his daily life My brother has a lab who is happy to get walked once a day, I guess all dogs are different.No doubt he his well loved but when he is in Elle's story he doesnt look energetic like you'd expect a lab at his age, plus you rarely see him playing with toys etc, their garden isnt exactly super dog friendly its more about insta goals. I'd expect a dog of Herbies breed to need two decent walks a day for his sake with two adults wfh with relatively easy workloads hope he gets enough exercise and they choose not to show it because its not glamours as they like to make out.
For the most part I feel like he is well looked after but that’s just my opinion on how I perceive it. I more worry about how her poor face will look from filler rather than Herbie x
