I have a rescue dog who came to me with torn ACLs in both of her back knees. She could barely walk. I found a product called Traumeel. It is an all natural anti-inflammatory, analgesic that is GREAT for muscle pains, aches, injuries, sprains, bruises, arthritis, muscle inflammation, etc. It has changed my dog's life. She is running around like a puppy until I get the money for her expensive surgeries. I use the liquid form and drop it on her food twice a day. This is perfectly safe for dogs and cats. It is actually a human product but has been successfully been used on animals for years.EC: Ingredients: 50 grams of ointment or gel contains: 0.75 grams each of Arnica montana 3X, Calendula officinalis 1X, Hamamelis virginiana 1X; 0.50 grams each of Aconitum napellus 3X, Belladonna 3X; 0.25 grams each of Bellis perennis 1X, Chamomilla 1X, Echinacea angustifolia 1X, Echinacea purpurea 1X; Millefolium 1X 0.15 gram; Hepar sulphuris calcareum 8X 0.125 gram; Mercurius solubilis 8X 0.06 gram; Symphytum officinale 4X 0.05 gram and Hypericum perforatum 6X 0.045 gram in a hydrophilic base.
