Now that I've read this, I will second what I said in your post and the email -- PLEASE have a TCVM vet look at this dog. The liver problem and the seizurey stuff are **RELATED** and a TCVM vet can help you. liver/seizures are often related (and I have a lot of experience with both liver dogs and seizure dogs) and a TCVM vet can help you without your dog having to be on the big seizure drugs (and those are HORRIBLE on the liver).
Please email me or PM me and I'll help you.
Yes, definitely do as the others have suggested. Also, double check that your dog is not getting into some of the foods or other products that cause problems. Raisins and grapes are BIG time culprits for this. Also some dog products do contain items which are toxic for dogs, such as Xylitol which is found in some of the dog mouth washes. Never use human mouth wash or toothpaste as this too can cause liver or kidney failure. Many dogs react strongly to flea and tick prevention or removal products. Other toxins are chocolate, tomatoes, onions, macadamia nuts, many houseplants, tylenol and ibuprofen products, alcohol, many household cleaners, antifreeze (deadly), caffeine, pesticides and herbicides. Some dogs cannot have garlic. Almost any of these can cause seizures, loss of balance, vomiting, and other symptoms similar to liver and kidney failure. Have you started using any news cleaners or sprays around the house? Has a neighbour been spraying his trees? Have you been using a new body product or prescription that your dog could be licking off your skin? All these are things you need to consider. Different dogs have different tolerances and not all dogs react the same way. Dogs with smaller body weights will often have greater reactions, but even that cannot be guaranteed. For instance, my sons large lab crosses cannot wear flea collars. They fall down, shaking.
As for diet. Remember that the dog food business is first and formost big business and is promoted that way. When you truly look at the ingredients, many of the most heavily promoted dog foods are not the best for your dogs - regardless of what they say in their advertisements. Try to avoid foods with grains in them, especially wheat, corn, rye, barley. The first ingredient of a food should be meat. The less 'meal' or byproducts in the food the better. Chickenmeal is usually meat or meat byproducts mixed with grain or other fillers. Cellulose is essentially paper which a lot of foods also use as a filler. If you have a small dog, feeding a really high quality food is not particularly expensive. Grains are not natural foods for dogs, and while vegetables are good - corn, which seems to be used in the majority of general foods as a filler - is one of the hardest for dogs to digest. Grains are frequently the source of allergies and skin problems in dogs. As are a lot of the preservatives in the foods. Oats are one of the least likely grains to cause allergic reactions. Many pet food stores are now carrying grain free dry and canned dog foods, and frozen raw diets. Raw diets are easily digested and leave less stool than dry foods, and are what dogs in the wild have been eating for thousands and thousands of years.
Symptoms this severe require veterinarian care, Prioritize trying to uncover any toxins your hound may be getting into. The comments in the post cover the important toxic stuff you should be looking for. Your mentioning of financial limits is the reason for my post, it is unlikely expensive natural dog foods and supplements are going to assist your dog in getting better. Focus on finding a vet clinic that is able to treat your dog for whatever money you can afford, if you wait for the liver to become critically damaged it may become an unmanageable health issue.
