Sorry I hadn't seen this one, but glad it's sorted. May be an idea to add a cranberry tablet to her food as a preventative measure.

Since I have been taking Warfarin I have found out that one should take care when taking or giving cranberry as it thins the blood and if the person or dog has a mild bleeding problem the administration could cause problems.

Good point Pita as all citric acid fruits and garlic can thin the blood however, the quantity used would have a minimal (if any) effect on the blood and I can't find any contra-indications at all on IVIS

As ever if in any doubt check with your veterinarian. Here's a chart that may help people evaluate;
Prevention
1. Since urinary tract disorders appear to have multiple causes and likely some other unknown ones, prevention lends itself to a holistic approach.
2. Diet - The type and quality of diet is an important factor in the increasing incidence of urinary tract disorders of cats and dogs.
3. What to Feed
o A portion of your pet's diet should be in the form of a moist food which approximates more closely the moisture/food ratio of their natural
prey. Choices would include, premium canned diets as well as raw or lightly cooked, frozen or dehydrated diets.
o Dry food should have high quality meat protein
listed in the first 2 ingredients, unless
contraindicated by other medical conditions.
o Protein, fats, oils and carbohydrates should all be
of high quality.
4. When to Feed. Cats and dogs are descended from top predators. They do not graze like sheep. Their digestive system needs a rest between feeds. Free feeding produces an elevated pH (alkalinity) which may encourage struvite crystal formation. Therefore, divide the daily ration 10-12 hours apart.
5. How Much to Feed
o The less volume your pet must eat to provide
optimum nutrition and meet energy requirement,
the lesser the amount of water is required for stool
formation resulting in higher urine volume. This
acts to lower the concentration of excess mineral
and protein (crystal formers) in the urinary tract
by flushing them out.
o Ensuring that you are not overfeeding promotes a healthy urinary system in 2 ways:
§ reduces waste matter which must pass through the kidneys and urinary system,
§ maintains a healthy body weight.
6. Water: Should have access to fresh water at all times. Natural whole food portion of the diet will also provide needed water balance.
7. Exercise
Sedentary and overweight pets are more prone to urinary tract disorders. Find toys that will stimulate your cat or dog to play on their own. Dogs should be walked at least twice daily - a good brisk walk or run.
8. Supplements
• A high quality oil supplement containing fish oil will provide vitamin A & D which promote a healthy urinary tract among many other benefits.
• A high quality powdered raw food nutritional supplement to counteract and replace deficiencies from over-processed food.
• Cranberry and blueberry contain Hippuric Acid which prevents bacteria from adhering to the lining of the urinary tract.
• Antioxidants - Vitamins A,C, E and selenium inhibit production of free radicals maintaining cellular health.
• Probiotics help to prevent pathogenic bacteria from populating the bladder and urethra.
9. Urine pH.
The diet should produce a moderately acidic urine pH 6.0-6.6. A 'natural diet' would do this as a matter of course being higher in meat, vegetables and fats, and lowest in grain. Occasionally, a commercial diet may sometimes be too alkaline or too acidic for a particular pet and diet change and/or supplementation is necessary.
10. The Magnesium/pH Relationship
Although urinary magnesium is necessary for the formation of struvite crystals, urinary pH is the most important factor. If magnesium levels are too low, calcium is released from your pet's bones which may have the unwanted effect of producing kidney stones. Low magnesium levels and acid urine inhibit the formation of struvite crystals but encourage the formation of oxalate crystals. On the other hand, high magnesium levels.

Always better to check if in any doubt.
