My name is Dizzy!

We met Dizzy at 3 weeks old when our friends fostered her (her litter was abandoned). We adopted her at 10 weeks into our home with a 4.5 yo bulldog. They have always been playful and snuggly. Dizzy has a sweet demeanor and we describe her as happy go lucky. She loves to snuggle any person who visits. She is submissive to other dogs and warms up to play with ones who want to. Dizzy has at times growled at our 2 yo who is learning to be gentle/calm with dogs. She is good with older kids who are predictable. Dizzy uses a doggy door 90% but fails to during storms or cold weather. She is trainable but has some obvious developmental issues - diverged eyes, drags a foot, turns circles.
Dizzy is 4 - at 3 y/10 mos she had a first episode of seizures. She was initially put on phenobarbital, had seizures 2 mos later, and is on keppra also. I am 8 months pregnant and, with a toddler also, we feel we cannot properly monitor and attend to Dizzy's care the way she deserves at this time in life.
