Hello Seeking advice on an issue which has arisen with my lurcher Jake. Not sure of his age - he's a rescue, somewhere between five and eight, I think. In the 16 months I've had him, he's always enjoyed plenty of exercise - we've been used to five walks a day, varying in time from half an hour up to an hour. Sometimes I'd have been happy to let one of the walks pass, but Jake always agitates to go out and frankly the exercise does me as much good as him. However, in the last ten days everything has changed. He still agitates to go out, but more often than not he wants to turn back home after a very short distance - usually no more than 100 yards. I was concerned about this when I became really aware of it, and last Wednesday took him to the vet. She wondered if it was his arthritis kicking in, and gave him a shot of an anti-inflammatory. It made no difference, and on Friday I returned with him to the vet. He was given X-rays and blood tests. The X-rays show that his heart is enlarged to a certain degree. The vet thought perhaps this was having an impact on his exercising (perhaps making him feel faint). She prescribed Frusecare, which I have been giving him since Friday. It has made no difference (although I guess it might be a little too soon). However, I'm not entirely convinced that this is a physical (or at any rate, solely a physical) matter. Although on the majority of occasions he turns back home after a short distance, on several occasions he has walked a reasonable distance, and several times has charged around the garden at a rapid rate of knots chasing a ball etc. Also, I think if it was a question of discomfort in his heart, it would not have suddenly developed, but would have been building up. This is not the case - the change happened virtually overnight. I did wonder when it first kicked in if it was fear - he doesn't like gunshots, and there were bird-scarers in the fields near where we sometimes walk. However, I'm not sure that stacks up ... his reluctance to walk seems to be unrelated to whichever particular walk he happens to be on. Sound familiar to anyone? If so, any advice? Thank you.
