My 3 and a half year old Yorkie has blocked year ducts.
She was put under a general anaesthetic and had them flushed.
They were fine for 2-3 days then the eyed were very tearful again.
The vet says its not bothering her and to leave it but ate their any other options?
Sometimes they look normal others they look very wet.

Just found this so copy and pasted:

Treatment

    Treatment of blocked tear ducts in dogs depends on the underlying cause of the condition. When infection is responsible, treatment with antibiotics and eye rinses is usually sufficient to clear the blockage and prevent complications. If blocked ducts are caused by allergic irritation and inflammation, exposure to the allergen must be avoided, and medication might be prescribed to reduce the body's reaction to the offending substance. Proper hygiene and grooming are essential to treat existing blockages and prevent the development of new ones. Irrigation of the tear ducts can be performed by your veterinarian. In severe cases, surgery to open or widen the ducts might be necessary.

Hope ur lil one gets better. All the Best :-)
