I have a 12 year old miniature schnauzer. She started dragging her hind leg and is now holding it up and won't put pressure on it. I have felt up and down it but she doesn't seem to be in pain. Could this be a stroke?

 

This is likely due to a problem in her knee, less likely hip or back. This requires a good neurologic and orthopedic evaluation from your vet. Thankfully, she does not show overt signs of

Labradoodle

 

The Labradoodle as a dog breed is still developing, and does not yet "breed true," i.e., puppies do not have consistently predictable characteristics.

History: 

The Labradoodle was first deliberately bred in 1989, when Australian breeder Wally Conron first crossed the Labrador Retriever and Standard Poodle for Guide Dogs Victoria. His aim was to combine the low-shedding coat of the Poodle with the gentleness and trainability of the Labrador, and to provide a Guide Dog suitable for people with allergies to fur and dander. Guide Dogs Victoria continue to breed Labradoodles today and Labradoodles are now often used around the world as Guide, Assistance, and Therapy Dogs as well as being popular family dogs.

Country of origin: 
Australia
Size: 
Medium
Grooming: 

Wool (with tight curls, and similar in appearance to that of a Poodle, but with a softer texture); Fleece (soft and free-flowing, with a kinked or wavy appearance); or Hair (which can be curly, straight or wavy, but is more similar in texture to a Labrador's coat)

Common ailments: 

Although most Labradoodles are healthy, they can suffer from certain problems common to their parent breeds.

Both Poodles and Labrador Retrievers can suffer from hip dysplasia, and should have specialist radiography to check for this problem before breeding. The parent breeds can also suffer from a number of eye disorders, and an examination by a qualified veterinary eye specialist should be performed.

Over the past couple of years, a number of Australian Labradoodles have also been found to suffer from Progressive retinal atrophy (PRA), an inherited disease that causes blindness, which occurs in both Miniature Poodles and Cocker Spaniels. It is strongly recommended that Australian Labradoodles be DNA tested for PRA before being bred.

A limited number of Mutigenerational and Australian Labradoodles have also been found to suffer from Addison's Disease

Temperament: 

Like most Labrador Retrievers and Poodles, Labradoodles are generally friendly, energetic and good with families and children (although as with any dog the temperament may vary between individuals).

My cat goes crazy every time I feed our fish. She likes to eat the fish flakes I give them. Will this hurt her? She cries and cries every time I open the fish food jar until I give her a few flakes.

 

As you likely know, cats love fish and fish flakes are food from the sea for animals in the sea-- so-- I am not surprised to find that she likes them. It is fine to share a few with her.
