    I just ordered tablets last night. Forget where I ordered from. When I get the package will let you know and will do a case study of the product and my 2 year old nuetured male. It's not just a female dog problem.

    I too am the proud owner of a acidic peeing, lawn damaging
    overly friendly hope to be a Great Chocolate Duck Hunting Machine Lab.

    Spoke with my breeder about the problem and like Enviro mention feed the dog some tomatos. I have been pour tomato juice over her food. Dog eats everything so getting her to feed on it is not a problem.

    Now if I only had green grass in the backyard i would know if it's working. Neighbors lawn is nice and healthy, and it does get dark out here at night. Looks like someone is going for a walk tonight with a full bladder.

    my female dog 6 months old kills the lawn when she goes my male dog is 5 and my lawn has been fine the whole time. she drinks plenty of h2o and pees constantly so it is definitely watered down pee. funny though any good spots of grass she digs up i think she hates the lawn and likes mud. she has also ripped out all my flowers she was laying in the tulip bed eating off the tops of all the flowers.
  4. 3 labs at my house

    I use 46oz of tomatoe juice and 13oz of vegetable oil, squirt a little bit on food

    really does help, when I use it!!!

    I have a male chocolate lab and a female black lab. The male kills the grass everytime he pees on the lawn. The female doesn't hurt it???

    There are a lot of theories as to why dog urine kills grass. I like the theory that it over fertilizes with urea. It is usually a problem with female dogs because they "void" all in one spot. Males spread theirs around on every vertical surface they can find.

    I also do not agree that altering the diet is a helpful idea. If you want to feed your dog more tomatoes, fine. Dogs are omnivorous and will eat everything, but don't count on it fixing the problem. If you could get them to drink more so as to dilute the urine, then you might have something going. But they are not your dogs are they?

    If you agree that the dog urine is over fertilizing the area, you can do a couple things. As outside professionals you don't have any control over forming the spot, but you can tell the homeowner to flush the area with water if they see it happening. Some homeowners have even trained their dogs to go out in the ground cover where it very seldom has any effect. My dog went in the ground cover all the time because we put his puppy training papers out there when he was a pup. He just got used to it.

    The second thing you can do, and this is more up your alley as professionals, is to scatter Granulated Urea Balancer (table sugar) on the area. You might wear gloves just to make it more mysterious. For a typical area, about 18 inches by 12 inches, I use a heaping handful and water it in lightly. The idea is to balance the excess nitrogen with excess carbon in the sugar. The soil microbes don't really care about the amounts of nutrients as much as they care about the balance. Excess urea moves the balance away toward too much nitrogen. The sugar restores the balance. Then the microbes are free to reproduce again and develop enough microbes to digest the "excess" nitrogen the next time.

    As an alternative for clients who want to see you spray something, you could mix molasses in water and spray that. I would still add sugar to the mix to get more carbon for the buck. Molasses is more expensive than table sugar. But the brown liquid is very "professional" looking, don't you think?

    I actually had grass start to grow in January because of sugar applications in December. Unfortunately those small green spots were as much of a headache as the dead spots they replaced. When they reached 8 inches tall, I broke down and mowed (in Jan!!!).

    This is too funny. I also have a female choc. lab. Is it possible that female chocs have become the dog of choice across the land? Yes- I have dog spots in my nice green St. Aug backyard.

    D_S_A, please contain yourself. Your ideas may be appropriate for a DIY homeowner board, but legitimate professionals are constrained on applications by very specific federal and state legislation and regulation. In my state, I must carry the label and MSDS (Material Safety Data Sheet) for everything I am applying to a client's lawn. For some commercial and industrial clients, I must supply these items to them in advance, because of OSHA regs covering their businesses.

    If I buy a jar of vinegar, and use it as a weedkiller, I would be subject to fines, because the vinegar is not labelled for use as a weedkiller. (Also vinegar jar probably has no MSDS.) I can buy ag grade chemicals for less than the same landscape chemicals, but again I'd be open to fine for using these items outside their label specifications. Do you have a source for sugar or molasses with labels for dog urine control? And an MSDS?

    Much effort has gone into regulating the for-hire application of landscape products, and we in the business like to respect that. The label is the law is what we have to work with. We can apply less than the label states, but we cannot make applicatioins at rates and uses not approved on the label.
  9. And the tomatoe juice with veg oil does work, I mix together, put in old ketchup bottle, and squirt a little on dog food!
