My dachshund got into a container of treats and is bloated

Last night, my cat opened a container of treats - soft chews and small dental treats - and knocked it on the floor where my mini dachshund (Charlie, 15, 8 pounds) had a big snack. I didn’t notice anything abnormal this morning - he was acting fine, drinking like normal, did not appear bloated. I gave him a smaller dinner than normal this evening and I only just noticed his stomach is distended. He’s been acting normal other than his stomach being tight. I can’t get to a vet until at least tomorrow. Is this something that I can just monitor and take him in if he seems distressed or should I try to get him in sooner?

Red bump on dog’s anus

Hello, my 4yo dog has this red, swollen spot on top of her anus. It appeared yesterday and seems a bit more red today. Could someone help identify this, and if it’s emergent/can wait to see a vet til Monday/doesn’t need to see a vet. I’m a first time dog owner and learning as much as I can. Thanks in advance!

What could that bump be on his lip?

Just picked this adorable lab up today and just noticed this on his lip is it just a scab? First time dog owner
