With this, urine will have a super strong odor that some describe as overly alkaline, like sulphur, garlic, or even rotten eggs. In any case, it will be very noticeable.
There are two main causes for this:
Dehydration
– If a Chihuahua is not drinking enough, this can lead to very concentrated urine, which is typically very dark and has a much stronger smell than normal.
Health issue
– Much more common, and the main reason for extremely smelly pee is some sort of issue or infection. At the top of this list is a urinary tract infection (UTI) or bladder infection.
Other signs include frequent urination, accidents or dibbling of urine, blood in the urine, signs of discomfort while urinating, licking at the genital area, and/or cloudy or discolored urine.
Other less common but possible causes include canine diabetes, bladder stones, tumor in the bladder, and blocked urethra.
