Green-UM Tablets for Dogs are a unique and innovative product designed to help control lawn burn and reduce discolouration and yellow patches on lawns. Using specially blended nutrients including Vitamin B-Complex derived from yeast, Green-Um Tablets are beneficial for your lawn and also provide nutrients to your dog. Green-UM is designed to change the chemical make up of your dog's urea, thereby eliminating the compound known to cause lawn burn. Green-UM also reduces plant and shrub burns. The tasty tablets are highly palatable and boast a high acceptance among dogs. Green-UM should be fed on a daily basis, particularly during grass growing season. For greener plants, greener shrubs and greener lawns, use Mark & Chappell's Green-UM.

25 Jury is still out . . .
Verified Purchase

By on 29 June 2017

Been feeding 2 a day as directed for each of my 2 dogs for a couple of weeks, can't say I've noticed any difference as yet. Lawn is still covered in yellow patches. Some old some new. I feel that it should be made more clear to owners that the packaging states 'effective when used in a protein controlled diet' whatever that means! Every dog has to have protein - mine are fed a cold pressed diet that is 25% protein - is this too much for these to be effective? If so it should say so - some guidance is crucial for a customer to make an informed decision as to whether these will work for them. Obviously this may be a get out clause for the manufacturer. It does not actually say what percentage of protein is an acceptable percentage for the tablet to be effective. SO jury is still out I'm afraid. At the end of the day these tablets are brewers yeast and yucca extract. Pretty expensive for what they are . . . . and so far ineffective which is very disappointing.

45 Does it work ?
Verified Purchase

That's what we all want to know ! However, my lawn is such a mess with 3 boistrous Boxers/Mastiff/Great Danes that I just hope that it would be a lot worse without this stuff. Packaging and delivery prompt and effective.

Q & A

Below are some recent questions we've received regarding VetIQ Green-UM Tablets for Dogs, including answers from our team.

Is there any side affects with green-ums

  • VioVet Staff

This product is a supplement so there are no listed side effects, however with any food-type product your dog can rarely be allergic/intolerant to the ingredients. This usually displays as diarrhoea or skin problems in the very unlikely occurrence it happens.

Can I give these to my cat?


I'm having this issue but it's with my cats. Would it be safe to give my cat one of these each day and if not, are there any cat-safe products that do the same?

  • VioVet Staff


Thank you for your query,

This product is absolutely fine to give to cats, similarly to dogs the dose is determined by the weight of the animal you wish to treat.

For cats between 1kg-5kg it is advised that you give one quarter of a tablet daily and for cats between 5kg-10kg you should give half a tablet daily.

I hope this helps you,

Mr Forsyth

How safe are green-um tablets in the long term

  • VioVet Staff

This is a sensible question and as with many things in life, it is impossible to give 100% assurance of complete safety. However most of the ingredients are present (perhaps in lower levels) in many dog foods and these are very unlikely to cause any bad effects. They are widely taken by humans too. The only unusual ingredient quoted is Yucca Schidigera extract, which is a plant product not found in most dog foods or supplements. It is regarded as very safe and is present in some human preparations too.

I would regard this as a very safe supplement and safe to use long-term, but if possible do not give it through all the year. (When there is heavy rain, especially when plants are not growing rapidly due to cold weather, the browning effect on lawns is less apparent. If the urine is diluted and washed away by rain, it will not cause trouble anyway and then can act as a fertilizer in fact.)
