And for some dogs, thats a problem. More use means more injuries and can lead to joint-related problems such as ACL (anterior cruciate ligament) tears and osteoarthritis. The unique property of Rose-Hip Vital Canine is the special patented compound which is activated during the drying process, which benefit joint health and general well-being of active and ageing dogs. Unfortunately, dogs cant tell us whats wrong, so its important to keep an eye out for the following symptoms that could indicate arthritis: Difficulty sitting or standing Favouring a limb Decreased activity or less interest in play Attitude or behaviour changes Reluctance to jump, run or climb stairs Weight gain Sleeping more Controlling pain and inflammation allows your pet to participate in daily activities and of course make life more comfortable in general. Osteoarthritis can affect dogs and humans alike, as it's a joint disease that frequently comes with aging, or even weight issues. So if you notice that your dog isn't jumping coming to greet you when you enter the house, then they may be affected. Its hard to see an active, healthy dog become debilitated by this condition.
