Should I be concerned?

I would be concerned since it’s been going on for two days. I think it would be best to take it to the vet.

Is he pacing and antsy? Is he eating? Is he defecating?

Have you watched him eat or drink? I could always tell when something was up with my dogs. Even when the vet couldn’t. I insisted on an X-ray one time, and I’m sure I pissed him off a lot, but the rock in his intestines showed up immediately. Trust your gut.

The more I think about it, I have to recommend taking him to the vet. It could be nothing more than anxiety, BUT his breed, gender, and age make him more susceptible to serious complications.

Panting is pretty non-specific but it can be an indicator of underlying disease (Cushing’s Disease, respiratory disease, heart disease). It can also be an indicator of pain or anxiety. But if he’s acting normally, is not lethargic, eating and drinking, it’s unlikely to be an emergency situation.

If he has stridor, he likely has laryngeal paralysis, which is not an emergency unless he gets overheated.

You need to check him for respiratory effort, which is subtly different than panting (like he’s working really hard, sucking for air, using his abdominal muscles to try to get air). That is an emergency situation.

Lift his lip and check his gum color – it should be a nice healthy pink. If he’s pale (whitish), cyanotic (blueish) or grey, it’s an emergency.

If he’s retching, like he’s trying to throw up but nothing comes up, it’s an emergency (bloat).

If his abdomen is noticeably distended or swollen, it’s an emergency (hemoabdomen or ascites).

Anytime their behavior changes is a red flag. Syz gave you great advice.

Aren’t boxers known to have breathing problems due to the way their respiratory passages are? (due to their facial structure, along with other dogs like Boston Terriers)

^ They are not one of the severely modified brachiocephalic breeds.. They are, however, known for being cancer factories.

Do you connect to the dog well?

He is laying down right now but his breathing/snoring is still pretty fast, kinda like 121212, in comparison to my MinPin who is laying right next to him and breathing 1…..2…..1…..2.

He was pretty restless last night and earlier today butat the time I was thinking it was because of the thunderstorm. Storm is long gone now but his breathing is still fast.

I know in the past he has had problems with his head shaking and random vertigo but it always goes away with a small amount of karro syrup.

I wish I could get in contact with my mom because she knows him the best but she is on a cruise ship somewhere near Alaska.
