Question: My dog just got diagnosed with crystals in urine and vet suggested changing diet….really don’t want to leave HALO since she loves it. Any thoughts?

Answer: Thanks for writing in. It is difficult for me to advise specifically on if a dietary change is a reasonable choice in your dog. Finding crystals does not necessarily indicate disease or a urinary problem. If your dog has signs of urinary problems (accidents, inflammation, etc) indeed something may be going on, however, a few things about crystals that you might want to discuss with your vet:

1) Normal dogs can have crystals in their urine. The presence of crystals does not mean the presence of disease—especially in a dog with no symptoms of bladder problems.

2) Crystals often form in the urine when the urine cools after it leaves the body. In order to accurately determine if a dog has a crystal problem, urine must be looked at within 10 minutes of collection from the dog. Urine should not be refrigerated or sit overnight in order to accurately evaluate for crystals.

3) In addition to the cooling of urine, some crystals form because the urine is very concentrated or has a high or low pH…again, this is not necessarily a “disease”

Good luck and I hope this was helpful information.

    Thanks for your question. Bad breath is usually related to an oral (mouth) condition although sometimes it can be caused by other organ problems. You may want to see your veterinarian to rule out the most common causes of bad breath such as gum / periodontal disease, mouth masses, kidney problems and lung disease. If your dog tends to be gassy or bloated or has a tendency to burp excessively he may actually have a digestive problem as the cause of his bad breath. In general, just like in people, the most common cause of bad breath is bacteria in the mouth and plaque and the best defense against it is daily tooth brushing. See my article on “getting to the root of bad breath”.

    Hope this helps. Good luck.
