Limping in 2 yr old Aussie/blue heeler mix

I need some advice. I have a female two year old Aussie/blue heeler mix. When she was a puppy she gained an excessive amount of weight due to me living on a 3rd floor apartment and pregnant with twins. We’ve since moved to a house with a fenced in backyard. We took her to the vet who did confirm she is obese. Her diet now consists of early morning feed of blue wilderness dry kibble for weight control and a dinner with mixture of same food and 1/4 cup of thawed frozen green beans. She is on a multi vitamin as well as a hip and joint supplement that she takes twice a day. Well, in the last 24 hours she has managed to do something to her right hind leg. She can’t walk on it. She limps around and whines when she puts any pressure on it. She doesn’t like for me to touch it so I can’t get a good look at it without upsetting her. And with her still being overweight, she’s having a hard time managing her balance on the other back leg without slipping as she’s walking and I’m terrified she’s going to injure her other leg or make the other one worse. My question is, is there anything here at home that I can do to alleviate some pressure or pain that she’s having?

Hello!  I'm afraid that this is difficult at home because I am unable to see whether the patient has a fracture, a torn ligament, dislocation, torn nail, foreign body, wound, snake bite, bone cancer  or something incredibly uncomfortable in the pad, for example, which would all require  different treatments.   Your dog sounds to be in severe enough pain that I would strongly urge an emergency consultation.  Always avoid giving pain meds yourself (not that you suggested it) unless cleared by your on call vet on the phone.  This is because some very common ones turn out to be toxic and problems have been caused that way.  I'm sorry not to give you the answers you want, but rapid veterinary assessment and rest ( in the very short term before getting there) may prove the optimal solution.

Obviously this is very easy for an online vet to say authoratitively to a pregnant woman in a flat and I apologise for this; I can hear you.  Thinking about that particular dilemma, some vets offer an ambulance service and others do home visits.  Furthermore I don't know what meds you have at home, but I can't prescribe and your vets may be able to based on a phone call, so it's definitely still worth the call.  Wishing you the best of luck with your twins and your furbaby - and please do, if you have the energy left, let us know how you get on.
