This is probably a daft question but I’d be grateful for advice from more experienced dog owners than me! 7 year old dog, wouldn’t settle last night, previously when she wouldn’t go in her crate this meant she has a bad stomach and didn’t want to be shut away. She didn’t need to go out overnight but stayed in her daybed and now doesn’t want to get up or eat, tail not wagging as usual but otherwise bright eyed and pleased to see me. Nothing visibly wrong with her, it’s only been since last night so I’m not about to rush to the vets but is there any guidance on how long to wait? She can be picky about food and has been known to not eat until very late in a day, missing a meal. How can you tell when your dog is ill enough to need the vet? If she was human you’d think, oh well a virus and if not better in a few days I might see the GP!
