My German Shepherd, Kaden was playing out by the pool today with my son, he is 15. They were playing spray the hose water right at his face and mouth. Kaden loves this , he passed on left over Pizza today while playing with him! But when he came in he looked like he was limping , later tonight it got worse, he is definitely favoring his front right leg. It looks like it got stiff after laying down and the more he is up and moving it the better it looks like he can move it. I palpated his legs and if anything it may be his right front shoulder area that he seems to be tender to touch nut nothing signifigant. Could he have slipped on the water enough to strain a muscle or pull a tendon or ligament kinda like a sprain that will get better on its own? The vet is closed until Monday morning. I am not sure whether to keep him off of it as much as possibkle or since it gets better with movement should encourage some moving and even massage it? Put ice on it? I just sprained my ankle, I am a nurse so when it comes to anumals I tend to trouble shoot and do what I would do for a human in a similiar situation. Anyone aware of any potential harm in waiting a couple days? What would a vet do anyways? I have spent a lot of money in the past on vet care that I could have easily have done myself at home in situations not totally unlike this, What can I do over the weekend? There is a 24 hour vet an hour and a half away from here, but they charge $100 off the bat for an emergency appointment then high prices for everything else they do and they want to do it all, x rays MRI's and labs etc... all at once and thney charge very high end vet prices for all of this I could easily spend over 500 or way more for this one plus they will add to all charges due to his large size for sure too. Any help I will greatly appreciate it! Is there any pain med like Ibuprofen I could give him for pain he weighs 110m lbs.? He seems sore, not yelping and he still wants to play etc but clearly he has hurt this leg.
