hi, I hope my reply doesnt come to late. I adopted the most active bulldog i have ever met.She is 2 1/2 and arrived with some real attention issues.Here is what works for her
1.a long walk EVERY day. I know you said this is impossible for you right now, so,maybe a family member, friend, kid next door,or someone you know on a diet who needs a walking partner. I know it sounds funny but its always more fun to walk with someone.
2. Training. mine gets actually exhusted from the mental stimulation after half an hour. it neednt be a workout for you. ( sit , stay , come , down, drop it)
3.Playtime with other dogs, several times a week.( you can bring a chair) Hyper dogs also though, so they will enjoy eachother. There are so many people out there just waiting to make thier dog tired too :}. Seek them out when they are walking thier dog.We take turns going to each others fenced in yards. If that is not available to you find a gated tennis court or basketball court.
4.Rawhide bones. They are something to do and great fun for the strong jawed bully. Just keep an eye cause they rip them apart easily and you have to throw away smaller pieces.
5.Take training to a new level, by teaching your bully funny tricks, Again, not physically demanding for you, but tiring for the stubborn bulldog. Mine jumps through a hoop and seeing a bulldog do it is hysterical.
I highly suggest profesional training since there will be a baby soon. good luck and dont give up sincerly Brooklily's mum
