Occasional constipation can be a normal occurrence in dogs like the Toy Poodle and other canine breeds. However, constant efforts to poop without any success can be dangerous. If you suspect your Toy Poodle is constipated call your vet. Signs of constipation in dogs include straining, dry stools, lack of pooping, mucous or blood covered stools, vomiting, lack of appetite, depression and possibly swelling around the anus. Constipation can be caused by a variety of things such as swallowed bones, swallowed hair, swallowed foreign objects, excessive fiber in the diet, dehydration, lack of exercise, trauma, stress, change in environment, change in hormones, change in blood potassium or blood thyroid levels, etc. If you notice any of the visual signs, please call your vet. X-rays may be needed to determine a possible blockage. For more details, talk with your veterinary clinic Pickerington, OH.
