Health problems linked to the Toy Fox Terrier

Conditions and what they can cost
ConditionWhat it isRelated costs
Luxating patella (slipping kneecap)Named by: AKC breed page, breed club screening [1]The kneecap slips out of its groove. Mild cases may only cause an odd skip in the step; severe cases can need surgery. [2]Surgery, median invoice: $1,284 (typical $578–$3,229) [3]
Dog X-rays (owner bills): $130–$300 [4]
Lens luxationNamed by: breed club screening [6]The lens of the eye slips out of place. It can cause sudden pain and glaucoma, so it is treated as an emergency. [5]Emergency visit (owner bills): $500–$1,600 [7]
HypothyroidismNamed by: breed club screening [6]The thyroid gland makes too little hormone, which can cause weight gain, low energy and skin problems. A daily pill usually controls it. [8]Dog blood work (owner bills): $60–$190 [9]
Weight gain and obesityNamed by: AKC breed page [1]Extra weight strains joints and raises the risk of diabetes and other problems. Measured meals and exercise are the cheapest fix. [10]Dog routine vet visit (owner bills): $130–$500 [11]

Costs are national figures from our sourced cost guides, not breed-specific prices. Being on this list doesn't mean a pet will get the condition.

Here is how the AKC breed page puts it: Responsible breeders will screen their stock for health conditions such as patellar luxation and eye disease. Obesity is a serious issue for Toy Fox Terriers. [1]

Health screening

The national breed club recommends these health tests for breeding dogs: Patella Evaluation, Thyroid Evaluation, Primary Lens Luxation(PLL). [1][6] If you are buying a puppy, it is fair to ask the breeder for the parents' results. OFA keeps a public database of many of them.

The UC Davis Veterinary Genetics Laboratory lists 1 DNA health test for the Toy Fox Terrier, including Progressive Rod-Cone Degeneration (PRA-prcd). [12] One health test costs $58 there. [13]

What to budget

For a small dog like the Toy Fox Terrier, a typical vet bill runs $273 – $1,110 (median $508), and surgery, when needed, runs $435 – $1,484. [14]

Lifetime cost, roughly. Our yearly estimate for an adult Toy Fox Terrier at US-average prices, before insurance, is $880–$1,400. Multiply that by a life expectancy of 13–15 years and you get roughly $11,400–$20,700 over a lifetime, before inflation and before any major illness. The low end is the ASPCA's yearly cost of care; the high end adds one typical vet bill a year. [14][15] It's simple math on sourced figures, not a quote.

Insurance and savings

The average accident and illness policy cost $836 a year for a dog in the US in 2025. [16] Timing matters more than the price. A condition that shows up before you enroll is usually treated as pre-existing and isn't covered. [17] Many plans also have a 6 to 12 month waiting period for orthopedic problems like knees and hips. [18]

Prefer saving instead? Putting money aside each month works too; see insurance vs a savings fund.
