Urinary Stones in Shetland Sheepdogs
Quick answer
Is a straining male Sheltie an emergency?
Yes, if little or no urine is coming out. Urethral obstruction becomes life-threatening within hours and must be seen immediately.
A stone sitting quietly in a bladder is a nuisance. A stone that has moved into the urethra of a male dog is a life-threatening emergency within hours.
Owners whose Sheltie has started squatting repeatedly and producing very little, who have found blood in the urine, or who have just been told after an X-ray that there is something in the bladder.

The obstruction emergency
This is the part that kills dogs, and it is worth knowing cold. A stone that lodges in the urethra stops urine leaving the body. Waste backs up, the bladder distends, and kidney damage and dangerous potassium levels follow within hours. Male dogs are at far higher risk because the male urethra is long and narrows where it passes through the pelvis and the os penis.
- Repeated squatting or lifting the leg with little or no urine produced. This is the single most important sign and it is routinely mistaken for constipation.
- Straining that produces only a few drops, or a thin dribble instead of a stream.
- Crying out while attempting to urinate, or an obvious change in posture to try to force it.
- A tense, painful abdomen, and in a small dog a bladder that can be felt as a firm ball.
- Vomiting, lethargy and collapse, which indicate the systemic effects and mean the situation is already advanced.
- Any of the above in a male Sheltie is a same-hour emergency. Do not wait to see if he manages later.
If any of these apply, call your vet or an emergency clinic now. The rest of this page is for the cases that are not an emergency.
What this problem looks like
Urinary stones in a Shetland Sheepdog are mineral concretions that form in the bladder or kidneys when urine is too concentrated, the wrong pH, or infected. Many sit silently for months. When they cause trouble, it is either as chronic irritation, with straining, blood and frequent small urinations, or as an acute obstruction, which is a true emergency and disproportionately affects male dogs because of their longer, narrower urethra.
Common triggers
- Urinary tract infection with urea-splitting bacteria, which drives struvite formation
- Persistently concentrated urine in a dog that drinks little or is fed only dry food
- Urine pH pushed toward one extreme by diet or by infection
- Infrequent opportunities to urinate, so urine sits in the bladder for long periods
- Individual metabolic tendency, particularly in dogs that have formed calcium oxalate stones before
Moderately common across small breeds and not a specific Shetland Sheepdog predisposition. Most Shelties never form a stone. Among those that do, recurrence rates for calcium oxalate are high enough that prevention becomes a permanent part of the dog's routine rather than a temporary measure.
Why this happens
Breed factors
The Shetland Sheepdog has no documented predisposition to urolithiasis, so the relevant breed factors are incidental rather than causal. Small body size means a small bladder and a narrow urethra, which raises the consequence of any stone that does form, particularly in males. MDR1 drug sensitivity matters because stone removal requires general anaesthesia and the genotype constrains the drug protocol. And a heavy double coat can obscure the wet, stained fur around the back end that would otherwise alert an owner to dribbling or blood.
Environment factors
Water and opportunity do most of the work. A dog fed exclusively dry food, with a single bowl in one room, and given four brief garden trips a day, produces concentrated urine that sits in the bladder for hours. Both of those are conditions under which minerals precipitate. Heat compounds it in a coated breed, because a mildly dehydrated dog concentrates its urine further. Infrequent toileting also allows any bacterial infection to establish itself, which is the starting point for the struvite pathway.
What you can do at home (once it is not an emergency)
When to talk to your vet
Go immediately, as an emergency, if a male Sheltie is straining and producing little or no urine, is crying while trying to urinate, has a tense painful belly, or has become lethargic or is vomiting alongside urinary straining. Urethral obstruction damages the kidneys and raises blood potassium to dangerous levels within hours and is fatal if untreated. Female dogs block far less often but are not immune. Book within a day or two: blood in the urine, frequent small urinations, urinating in the house in a previously clean dog, or licking excessively at the genital area. Book routinely: a urine test as part of senior screening, since silent stones are often found incidentally.
At home, alongside your vet's plan
- Add water to every meal, generously, since this is the most reliable way to dilute urine in a dog that will not drink on demand.
- Provide several water bowls in different rooms and refresh them daily, and consider a fountain if your dog prefers moving water.
- Increase toilet opportunities rather than only extending walks, since it is the frequency of emptying that matters, not the distance covered.
- Look at the urine periodically, on snow or on a pale surface, so blood or unusual colour is noticed early.
- Insist that any retrieved stone is sent for laboratory analysis, and keep the report, because it dictates the prevention plan.
- Have the MDR1 test done in advance so an emergency anaesthetic does not begin with an unanswered question.

What to expect, and how you know it is working
Dissolving struvite stones on a therapeutic diet typically takes several weeks to a few months, with imaging checks along the way to confirm they are shrinking. Surgical removal is a single procedure with a two week recovery. Prevention is indefinite, and for calcium oxalate formers, monitoring urine every few months for the rest of the dog's life is normal. Recurrence within two to three years is common enough that it should be planned for rather than treated as a failure.
Success is a dog that urinates comfortably, in a normal stream, without blood, and whose follow-up imaging stays clear. Longer term it is a household that has quietly built water into the food, put bowls in three rooms and increased garden trips, so prevention happens without anybody thinking about it. For a recurrent former, success may simply be longer gaps between episodes.
Two stones, two completely different plans
The great majority of canine urinary stones fall into two families, and identifying which one you are dealing with determines everything that follows.
Struvite stones form in alkaline urine and, in dogs, are usually driven by a urinary tract infection. Certain bacteria split urea and raise the urine's pH, and the minerals precipitate around the infection. The good news is that this makes them a chemistry problem with an infectious cause, and in many cases they can be dissolved by treating the infection alongside a therapeutic diet, without surgery at all.
Calcium oxalate stones form in acidic urine and are not driven by infection. They cannot be dissolved. If they need to come out, they come out mechanically, and once a dog has formed one it is prone to forming more, so prevention becomes a permanent project rather than a course of treatment.
Your vet works out which is which from urine pH, from what the crystals look like under a microscope, from the stone's appearance on imaging, and definitively from analysing a retrieved stone in a laboratory. That last step is worth insisting on. A stone that is removed and thrown away has taken its most useful information with it.
Mistaken for constipation on a Sunday
Gareth's Sheltie, Alfie, spent a Sunday morning squatting repeatedly in the garden and producing nothing. Gareth assumed constipation, gave him a little extra oil on his food, and planned to phone the vet on Monday. By mid-afternoon Alfie was restless, would not settle, and cried when Gareth lifted him. That was what finally prompted the call, and the out-of-hours vet told him to come straight in. Alfie was obstructed by a small stone lodged in the urethra, with a bladder the vet described as being like a tennis ball, and his blood potassium was climbing. He was unblocked that evening, hospitalised for two days, and had the stones removed surgically the following week. The laboratory came back with calcium oxalate. Alfie is now on a therapeutic diet with water added to every meal, has three water bowls, and gets four garden trips a day rather than two. Gareth's practice sent him home with one line written on the discharge sheet: straining with nothing coming out is never constipation.
Key takeaway: The difference between a urinary emergency and a bowel problem is whether urine is actually being produced. In a male dog, straining with no output is a same-hour emergency, and hours are exactly what is at stake.
Frequently asked questions
Are Shetland Sheepdogs prone to urinary stones?
Stones do not appear on the breed's documented health list, which covers Collie Eye Anomaly, MDR1 drug sensitivity, dermatomyositis, hypothyroidism and patellar luxation. Shelties form stones at roughly the rate small dogs generally do, which is not negligible, but this is not a breed-defining problem.
How do I know if my dog is blocked or just has a urinary infection?
Both cause straining, but a dog with an infection still produces urine, often small frequent amounts, sometimes bloody. A blocked dog strains and produces essentially nothing. If you are unsure, treat it as a blockage and go in. Getting that wrong in the other direction costs a dog its life.
Can stones be dissolved without surgery?
Struvite stones often can, using a therapeutic diet plus treatment of the underlying infection, over a period of weeks. Calcium oxalate stones cannot be dissolved by any diet, and removal is mechanical. This is exactly why identifying the stone type comes first.
Does my Sheltie need a special diet forever?
For calcium oxalate formers, usually yes, because recurrence is common and diet is one of the few levers available. For struvite, the diet is often a treatment course rather than a life sentence, provided the infections that caused them are prevented. Your vet sets this based on the stone analysis.
Why does MDR1 come up in a urinary case?
Because stone removal means general anaesthesia, and MDR1 drug sensitivity is documented in Shetland Sheepdogs. The genotype determines which sedative and anaesthetic agents are appropriate. Have the test result on the file in advance, since a blocked dog arrives as an emergency and nobody has time to wait for a swab result.
How do I get my Sheltie to drink more?
Dilute urine is the most reliable prevention there is. Adding water to food is the highest-yield change, since it goes in whether the dog is thirsty or not. Multiple bowls, a pet fountain and wet food all help. Aim to make dilution a feature of the diet rather than something the dog has to choose.
Quick answers

What are the two main stone types in dogs?
Struvite, which is usually infection-driven and often dissolvable, and calcium oxalate, which is not dissolvable and tends to recur.
Health
Should a removed stone be analysed?
Always. Without laboratory analysis you cannot know which prevention plan applies, and prevention is most of the long-term outcome.
Costs
What does stone surgery cost?
Imaging, surgery and hospitalisation typically run well over a thousand dollars, and an emergency unblocking costs more again.
Living
Does adding water to food really help?
Yes, more than almost anything else. Diluting the urine reduces the concentration at which minerals precipitate, and food is a reliable delivery route.
