Does anybody have any tricks for preventing or correcting dog urine damage in turf? Shooting the dog is not an option.:laugh:

I second that motion !!!

It scares me..how many people think "lime" is the MIRACLE PRODUCT for their lawns because "somebody said so"... and don't even go about checking the soil pH at ALL.

But aside from it's other reputable and noble use of raising pH in acidic (low pH) soils...a bag of pelletized lime is good to have around for any dog owner, to help 'nullify' the acid-pee the *el-cheapo dog foods can cause a dog to produce.

*(Yes...it's true !!!
If you switch your pooch over to a MUCH better grade of dry dog food like "Iams" or "Science Diet"...your "nuclear pee" :cry: problems in the turf will likely begin to diminish.)

I've heard tomato juice in the dogs water will help but my dogs won't drink it.LOL

Chewtabs are hocus-pokus. Guys at Purdue University say they make the dog thirsty to cause them to drink more & "water" down the pee...Except that doesn't work & it makes your dog have to pee more often, causing MORE spots:cry:

Since it is thought that it is the nitrate's in the pee that burn the spot, there is not much to do to nutralize that;) (Had PH tested of the burned areas & it was not high, so why would lime work??)

Any pet store will have several types of pills to help protect the lawn. The customer might want to try them. I doubt that it will help. Hocus Pocus, I am sure.

Figure 1. The patches of greener, more vigorous
turf are caused by animal urine.
Figure 2. A dead, brown “crater” surrounded by
a dark green turf ring characterizes classic urine
damage.
Animal urine can aggravate anyone attempting to
maintain a uniformly green, aesthetically pleasing
lawn. Concentrated urine from wildlife such
as foxes, deer, and geese can discolor, injure, or
severely damage turf. But for homeowners, pets
(particularly dogs) are the most frequent cause of
patches of darker green and/or brown turf, that are
often concentrated in a particular part of the lawn.
The exact mechanism of urine injury is not
completely understood. However, concentrated
salt-based fertilizer spills cause turfgrass damage
similar to animal urine. This has lead many to
believe that animal urine contains highly concentrated
salts that dehydrate the turf.
Symptoms of Urine Damage
Animal urine can damage any turfgrass species
in any climate. The most severe damage seems
to occur where soil moisture is low and turf is
poorly hydrated. Prolonged dry, hot weather may
exacerbate the damage, especially for cool-season
turfgrasses (Kentucky bluegrass, perennial
ryegrasses, and tall and fi ne-leaf fescues). In
severe cases of urine damage, turf receiving the
highest concentration of urine typically takes on a
gray-green, wilted appearance, which rapidly turns
straw brown (Figure 1). Turf death may occur in 24
hours or less in hot, dry conditions. Dead patches
of turf do not always appear, but when they do,
there is a central crater of brown turf, 3-6 inches
in diameter, surrounded by a dark green ring, 6-12
inches in diameter (Figure 2).
This combination of very green and dead brown
patches may persist for several weeks depending
on the vigor of the surrounding turf and its capacity
to recover and fi ll in. The greening effects are

most noticeable in malnourished turf because the turf
responds quickly to the urine’s readily available nitrogen.
Greening may also occur in well-fertilized turf
areas. For cool-season turfgrasses this is particularly
evident during the early spring (March), midsummer,
and late fall (November and December) when the turf
is not actively growing (Figure 4).
Several common turfgrass diseases (such as dollar
spot, summer patch, and necrotic ring spot) may be
confused with animal urine damage because they
affect turf during the warmer months and form similar
patches and craters. For more on these and other
turfgrass diseases, visit the Purdue Turfgrass Program
publications Web site: http://www.agry.purdue.
edu/turf/publicat.htm#BP. Animal urine turf damage
can be distinguished from these diseases because
there is no cottony mycelium present during the early
morning and dying leaf blades do not appear watersoaked
or mat down like those affected by fungal
infections. Furthermore, urine damage almost always
has a dark green, actively growing perimeter.
Behavior May Contribute to Damage
Of the common household pets, dogs tend to damage
turf most. Cats are generally not a problem since
they prefer gravel or sand-like substrates to void
rather than lawns. Among dogs, females are more of
a problem than males, due to differences in voiding
behavior. Females typically squat when they urinate
and male dogs lift their legs (Figure 3). However,
young dogs of both sexes normally squat to urinate
and the typical leg lifting and marking behaviors of
male dogs do not become prevalent until dogs are
about 1 year old.
In addition to squatting, female dogs are less
discriminating about where they void and typically
release all of their urine in one concentrated location.
Figure 3. Puppies and mature females squat when
they void, concentrating urine in one location.
Figure 4. Concentrated dog urine can be particularly
damaging in months when the turf is not actively
growing, such as early spring.
Speculation abounds among pet owners regarding
how the constituents of female dog urine damage
turf. Some suggest that the urine’s pH, or that the
hormone content of spayed vs. non-spayed dogs’
urine may infl uence the problem. To date, however,
none of these factors has been thoroughly tested or
proven to contribute to turf damage. Thus, the more
important role is probably the voiding behavior of
female dogs.
Practices That Help Minimize Damage
The only way to ensure animal urine does not damage
turf is to completely remove the pet from the
lawn, which for most pet owners is simply not practical,
so consider the following management practices:
1. Keep the pet off the most visible parts of the lawn
and/or train the dog to use one designated low-visibility
area.
2. Water the portion of the lawn where the dog has
voided with a watering can. This helps minimize
serious damage but may not completely eliminate a
greening response.
3. Walk your pet in a neighborhood common area,
dog park, or other, less aesthetically important turf
area.
4. Maintain healthy, vigorous turf that can easily
recover from damage. Some of these maintenance
practices include:
- Mow the lawn as high as practically possible; 2
to 3 inches is appropriate for most lawn turfgrass
species.
- Follow an environmentally responsible, properly
AY-327-W Animal Urine Damage in turf
IL-IN TW 61
timed nitrogen fertilizer program (nitrogen is the
nutrient most responsible for green leaves). This
will help keep the area affected by urine from
being dramatically different in color from the rest
of the lawn. Although the turf affected by pet urine
may respond to urine nitrogen, this does not
necessarily mean that the lawn requires fertilization.
Modest nitrogen additions may mask urine
symptoms but nitrogen should only be applied
when it will benefi t the turf, and not during times
when the turf is dormant and nutrients will be lost
to the environment. For more detailed information,
refer to Purdue Extension publication, AY-22,
Fertilizing Established Lawns (http://www.agry.
purdue.edu/turf/pubs/ay22.htm).
- During times of drought, follow a deep and infrequent
lawn irrigation schedule. Maintain adequate
soil moisture and keep the turf hydrated to minimize
damage and encourage damage recovery.
Other Remedies Probably Ineffective
Some commercially available products claim they
can repel animals from urinating on particular areas.
However, these products have not been proven to be
effective.
Also, a number of self-proclaimed pet authorities
suggest a variety of dietary modifi cations (usually in
pill form) to manage animal urine turf damage. Some
products purportedly manipulate urine’s nitrogen
content or affect the animal’s liquid consumption.
Most of these products simply cause the pet to drink
more water, thereby diluting the urine’s nitrogen content.
An added side effect is that the animal will need
to urinate more frequently, increasing the potential
for “accidents.” Furthermore, using these products
is potentially dangerous, and you should consult a
qualifi ed veterinarian before initiating such a remedy.

Had PH tested of the burned areas & it was not high, so why would lime work??

That's because the solubility of the "pee" in the soil was so great that it did it's damage and "left the scene of the crime" :walking: ...just like that!

For a true barometer :

Get a small box or roll of litmus paper at the drug store, and then let your dog pee on THAT .....after eating "El-Cheapo" brand dog food for a few weeks !
Very likely....Your results will show in the direction of extreme "RED", which would indicate acidity.

(Blue indicates alkalinity, by the way.)

Nice post !
Good to see some of the tuition $$ going to some good use ! :laugh::laugh:

Purdue...or any other university for that matter, would never bring up the subject of "inferior" grade dog foods...because they certainly know they would be pressed at some point to give specific examples of what they'd be talking about !

NOT !

If acidity of pee did it's job & "left the scene of the crime", then what use would it be to lime the spot after the fact?:hammerhead:

The whole idea is not to wait until "after the fact", when the turf is completely DEAD !!
(back at ya ! :hammerhead:)
:laugh:

Throwing powdered or pelletized lime down on a piece of turf immediately after you notice that it's been attacked by dog urine... can often "rescue" that section of grass from dying in the 1st place.

He said they apply lime ON dog spots. This implies that it is being put on AFTER the damage has been done.

As far as the cheap dog food goes... I feed my Golden Retriever Eukanuba, and he pisses kilz all! I might as well bottle it up & use it in place of round-up:laugh: We used to feed him Iams, but Vet recommended changing foods when he started having seizures.

So, the cheap dog food theory doesn't hold up-at least in my case.

I've got a customer who has a 30k sf backyard & looks like dog pees in a checkerboard pattern all across it:laugh:

It seems to me that dog spot damage is consistent with nitrogen burn. (That would make sense, since we excrete nitrates we consume through our pee)

It is excess nitrogen from the dog pee and has nothing to do with the PH level. This has been studied to death. Look up dog pee on a university web site and they all report the same. If you see the dog pee water the area down to dilute the pee.

Whoa...no kidding ! :confused:

Seizures huh ?...but not because your goldie was eating "Eukanuba", right ?
My gut instinct is that there had to have been "something else" going on with your dog to cause such a ultra-hyper condition....in an already very excitable breed like golden retrievers.

Far too much info for trying to correct a problem that can't be corrected unless YOU GET RID OF THE STINKIN DOG. You can't have nice turf + dog. You can have one or the other, you choose, simple as that.

I've had good results with the GreenUms products. Funny how myself, my customers and a lot of people on the net have had good results. The yucca in these displaces the nitrates in their pizz...

I think the lower quality dog food theory does hold weight. Most lower quality foods and some "better" foods (check the Pukanuba bag) contain corn gluten meal as filler (among rice and other ingredients). Dogs can't digest it, so it has to come out somehow. That corn gluten meal contains 9-10% N. Over time in the same spot, it's going to burn.

No, He still has a seizure about twice a month. They told me that is very common in dogs, especially his breed & age (~9 yrs. old) He could take meds, but may hurt his heart.
