My dog keeps swallowing and licking lips. Is he sick?

Updated on September 23rd, 2025

Pet's info: Dog | Chihuahua | Male | unneutered | 3 years and 10 months old

Why does my dog keep swallowing constantly? It's 3 AM and I have kept waking up because my dog seems visibly uncomfortable, he's usually knocked out pretty quickly and stays in one spot (sleeps on my bed) but today he's been moving around and it seems he is swallowing and licking his lips a lot like maybe 4 times per minute and he may take short like 5 minute breaks. I was reading about dog bloat and have taken a look at his stomach it doesn't seen any different from before.

Swallowing a lot and licking lips is due to nausea. Bloat is very uncommon in a small breed dog like a Chihuahua so that is not likely to be the cause.

I suggest you have Junior examined by your vet as nausea is a very vague symptom and not specific for any one disease process or illness.
