So my 3 year old beagle Sadie has gotten much less active in the past year. Last april, she got a hernia that had to be surgically removed and she couldn't walk for a few weeks. Then in November her anal gland ruptured and she had surgery to fix it, which made running difficult again for her. She's all healed up now, and our vet says she is medically fine. Now she's just lazy, and even at the dog park she just stands around. Any ideas how to get her active again and playing with us?
