Everything you describe (With the Leg) is classic for "Luxating Patellas".....You can google to read more......If this is what your dog is experiencing, Cage REST will do nothing for it! Very common in small dogs & the kicking out is their way to put the joint back in.....A good Vet will be able to feel the Luxtation just with an physical examine......Very Simple!!!!
Sounds like yours is just guessing!
The Heart Rate is completely different & I would start with an ECG to check his heart function......At 10 years old, Heart Disease is not uncommon......Your regular Vet should be able to do it....Then, go from there...Good luck & let us know....Karla
I worked for a vet for 8 years. I seriously doubt that any heart condition he may have has anything to do with his leg. When your vet told you 'rest for 6 weeks' she actually meant to literally not allow ANY unecessary movement for 6 weeks. I had to do this with one of my cats, and it worked, but it was HARD to do, always feeling bad for keeping her in a cage. If you have a kennel, that is best: A mid-sized 'carrier' or kennel large enough for your dog and food and water. Carry him out to go potty, allowing minimal movement, and carry him back in, straight to the kennel. I won't lie: this is not fun for you or your dog. You might want to request a calming medication for him from your vet, so that he remains slightly sedated, and more comfortable caged up. Blessings for you and your dog - Blu
