Hi, Diesel is our 5 year old Dogue de Bordeaux and we have had him for a year. We rescued him and he settled in pretty fast. Past couple of days, he has been looking very nervous around me when my girlfriend is present and he will keep his distance and stay out my way - only when she is around. I must add we 14 -15 weeks pregnant and his behaviour has only changed in the past 2 days. At first I thought it could be because I had to clean him the other day when he was in extreme discomfort. He had a bit of constipation and what he tried to get out had collect around his rear end and was attracting flys. He could not sit. So I had to clean him as gentle as I could but he really was not happy, kept trying to walk away. Never growled or anything though. So in my head up until yesterday I thought I had lost his trust from having to put him through a bit of a uncomfortable 5 minutes. That night we were both saying goodnight to him while he was in his bed like we normally do and he growled under his breath to me so I just backed off from him. The next day in the morning, he seems fine and we go on a walk. I get home from work first, he is mega excited to see me, jumping up and then we play a bit of tug of war. We then go for a walk which he goes crazy for when he hears the word and off to the field we go. Get home, bit of a groom and he is cool. My other half comes home and he is attached to her, however if I come into the room he sulks away into the corner of the garage and keeps his distance. I try to bribe him with some of my own food which he takes but again is very shy and close to cowering near me. Next morning, girlfriend is up earlier and getting ready to go to work, and Diesel is waiting out side my bedroom door for a walk and happy as ever when I come out. Do the walk, then back to a sulky dog in the garage. Really cant read him right now! At first I thought I lost his trust because I might of hurt him cleaning him up, but then when I got home and he was totally different - then switched when girlfriend got home makes me think the pregnancy might be playing a part on him? Sorry for the ramble, if anyone has any ideas that would be cool! Thanks.
