We haven't been to the beach very much during the summer due to Ram's increased panting this year. The swimming hole has been a better option as there are trails with lots of shade.
During a visit to the vet a couple of weeks ago for a Tramadol refill he was panting because of treats but she didn't hear anything in his panting that sounded like LP or felt it was necessary to do any tests, he's just an excited lunatic. Although she did suggested that we try Metacam for 2 weeks to see if the panting was from pain and then test his blood. After the 2 weeks his blood tests showed an elevated sdma value over his previous tests from the spring. I didn't notice any difference in his panting or movements while he was taking the Metacam so I'm not taking the risk and we've gone back to Tramadol. We're still doing the underwater treadmill once every three weeks with laser for his elbow and a huge bonus is that they do his nails too.
