AH CAN SMELL SAUSAGE ROLLS ! <| sep |> First I would learn some proper back sparing movement . Learn how to bend over properly , and keeping a neutral spine when at work . Work on your posture . Always sit and stand with good posture . Sometimes working on your posture also means strengthening certain muscles and increasing mobility in others . Careful of your form when doing exercises . Basically if it hurts your lower back feels strained , you ' re doing it wrong . Losing weight would help , but won ' t be a cure . I would suggest you try doing the McGill Big 3 exercises . <| sep |> At a time like this ? ? Definitely Leah . Kevin can wait . <| sep |> I ' m trying to be a nice person . It ' s hard , but I ' m trying , guys . <| sep |> That is a difficult question , a lot of people will say go and get a mutt . Mixed breeds also often suffer from health issues . The greater the variety in the ancestry , the smaller the chance of problems caused him inbreeding . But you can never exclude your dog from heaving congenital health issues , even the most natural breeds suffer from them at some level . I think one should try to find a dog that is average . Average in height , length , coat structure and color , maybe even behavior . The larger and heavier the dog the more chance that it will get skeletal and heartproblems for instance . That ' s why many large breeds only live for 8 or 9 years . Dogs that are too small often have a fontanel that doesn ' t close resulting in a soft spot on top of their heads . When the skull is too short you often see that their tongues don ' t fit in their mouth completely , or their eyes pop out when there ' s to much pressure on the head . Dogs that have long backs often suffer from back problems . I could go on but I think you get the point . Try to avoid extreme features in body types . I have a mixed breed dog , she is part sighthound . Sighthounds are pretty average in size and weight . She was found as a stray in Spain . Dogs in Spain were and still are used for hunting . Dogs that are bred for working are often healthier . I got her from a shelter , one of the advantages of getting a dog that is older is that many health issues are already known . I ' m sorry I can ' t explain it better than this , English is not my native language .
