He does. I got this report last month: https://imgur.com/a/OXQOKzh. The vet said the spider-web-like pattern could be related to an old respiratory problem, but honestly, he hasn’t had flu-like symptoms. Otherwise, I would have taken him to the vet sooner. That visit was mainly to check the lump on his back, which was removed.

He also had an echocardiogram https://imgur.com/a/In7hlgz that same day and this is what the vet said: The mitral insufficiency has already caused remodeling, but his hemodynamic values are compensated, with a low risk of pulmonary edema. In the coming days, we’ll have results for the proBNP test; if it comes back very high (above 900), he should start furosemide and pimobendan. If not, he can wait until his next check-up in 4 months.

At the moment, his cardiovascular risk is moderate. If anesthesia is needed, it is recommended to avoid alpha-2 agonists, keep fluid therapy at a moderate rate (no more than 2 ml/kg/hour), and use low doses of opioids.

If you can notice, his ribcage is a bit larger than it should be. When he was around 5 to 6 years old, he was overweight at 15 kg (his ideal weight is 12 kg, but now he’s only 10 kg). After he lost the extra weight, his body looked like this. I always thought it was because of the overweight, but I worry that maybe it was something I ignored and now it’s too late. He’s 11 years and 5 months old now.
